Skype Chat 4.5: Andy Lomas

 

On Tuesday we had a visit from Andy Lomas, a former mathematician turned creative computer artist. His work stems from an interest in dynamic systems simulating biological growth. An interest stemming from his encounter with the work of Darcy Thompson, particularly his pioneering book Growth and Form, became after a period in the film and television industry, curiosity in what can be done that could not be done before. Lomas works on the edge of control and predictability wanting to be surprised rather than being in control of algorithms whose outcomes are directed by the exigencies of the film industry.

He sees himself more as influencing than controlling events when setting up his algorithmic simplified systems, which while not trying to replicate nature, bear strong correspondences with biological rules of growth.

The systems he works with are bounded in themselves and do not relate to an outside environment. The parameters or rules of engagement between cell entities are contained within and between the cells rather than communicating with an exterior world even though some simulation, such as how much light falls on a cell try to emulate real life conditions.

Something that struck me during the talk was how the artistic domain gives him the freedom to experiment and play with mathematical models and their aesthetic outcomes. However, it does seem to stay within that sphere, the personal perspective. His relationship with the work is more that of a craftsman than an artist. He is curious about his methodology, he extends the limits of what he is doing, he controls the material with mastery. However, the work itself says little about the person than made it other than their obvious skill. Little of him comes across in the work as algorithms do not in and of themselves depend on any particular person or thing that either generates them or uses them. They are autonomous abstract entities depending only on being implemented in some way to have any meaning. Taking Margaret Boden’s idea of creativity, the results are certainly creative, as for artistic, perhaps that is in the gift of the viewer.

What does this tell me about the work and the worker. The work can certainly be viewed as art, but is Lomas working as an artist or a craftsman? All depends on his intentions and when asked what these were, we were left wondering if he himself knew. He enjoys making the animations and work arising out of them, and he does appreciate their aesthetic appeal, but I for one would want to look more into the content itself of the work. What does it say about me, the world, society and how does it function in different contexts?

All these questions were left mute by virtue of Lomas’ immersion in the process itself, often by necessity. I feel that it is not enough for something to be art simply because it is creative. And if context is everything, perhaps what happens is that the work is taken up as art by others, leaving its maker behind so to speak, personally, as a creative rather than artist.

If all this seems rather harsh, I am only applying the same criteria I have applied to myself. As someone who studied sciences, I have often been frustrated, no infuriated, by how artists all to easily append the label, art science to what they do, appropriating the domain of science without really understanding what they are dealing with. That is why I made the decision not to do scientific art, i.e. appropriate techniques and methods, illustrate ideas, pretend to be doing science that in some way turns into art. All an artist can do is draw inspiration, be influenced by, illustrate yes, the scientific. Likewise, a scientist cannot be an artist simply because they make something aesthetic or useful to artists or illustrates some artistic trope. A scientist can be influenced by, borrow from, be contextualised by art, but that in itself is not enough.

For a scientist to be an artist, they must think as one with every fibre of their body and likewise if an artist wishes to be a scientist they need to fully understand the paradigms that govern the scientific mind. The two domains work so differently that one has to give way to the other. You can be a poet and a scientist, a scientist and a painter, but you cannot be both at once. Science relies on being replicable and independent of personal input, art conversely is deeply personal in terms of the ideas and relies on an element of uniqueness, aura. Artists that attempt to remove any trace of the personal and make an idea or method doable by anyone, still function under artistic paradigms and do not fall within the scientific. Likewise, an electron photomicrograph of a pollen grain, however beautiful, cannot be a work of art unless it is transformed to say something other than what it is. In neither scenario is there a transformation from one paradigm to the other. They both enter the sphere of the other but cannot be the other. It is a nuanced view that can be argued with, but nevertheless, is serves to illustrate the point that science and art are separate, yet have an entangled relationship.

This places Lomas’ work in somewhat of a no man’s land, albeit a comfortable one. The renderings of the algorithms can be seen as art just as Blosfeldt’s photographs are considered artistic photographs. However, in the case of Blosfeldt, the images were made for a very practical purpose, as source material for art students. The fact that they have entered into the artistic canon does not necessarily make Karl Blosfeldt an artist at the moment of making them but more of an artisan. The art resides in the way the photographs have been received and experienced. Similarly, Lomas’ renditions are a search for the limits of what certain algorithms can do and how resolved the animations can become. They are visual illustrations of mathematical curiosity, how they are perceived is another journey towards an artistic conversation which does not necessitate knowledge of their maker. This in some way is what he said adding that he would be only too happy to explicate their genesis to those interested.

Perhaps one day Lomas will consider the wider poetic implications of what he has done and engage new poetic criteria which will undoubtedly alter his process and conceptual horizons.
 

Uniformity, Local Conditions and Culture

 

 

I wrote the following as part of the previous post on writing. When revising what I had written it seemed a bit of a non-sequitur. It was more about creating a context for linking writing about science with writing about art. The ideas I touch on here need expanding but I think it serves as a note-to-self for the future. 

The scientist has to assume, indeed believe in the uniformity of the universe, otherwise no finding would have applicable value elsewhere, everything would be relative. What this means is that the laws of physics apply equally wherever you are located in the universe, there is no place where the laws might be different or behave in some other way. This is not to be confused with the theory of relativity and its stated relationship between mass, energy, time and space which is always the same, with the speculative exception of  black holes or the very beginning of the universe when the ‘Big Bang’ occurred. If the universe were not uniform regarding to the laws of physics, there would be no possibility of confirming scientific theories or indeed refuting them, for there would be no basis for predicting outcomes according to a hypothesis, phenomena would be subject to local laws only. This assumption is one of the basic principles of the scientific method and experimental philosophy and so far has not been refuted.

The religious person must also believe in uniformity regarding god or gods, otherwise there could not be an ultimate authority for morality and therefore behaviour could not be regulated. Religions rely on a uniformity of consequence, justice, compassion, love, etc. as a central tenet to their universality. Correspondences and conflicts between religions come down to what they have in common as well as how they differ in their universal applicability as much as ritual practices, credos and the like. Likewise, an artist has to trust that there are universals that when applied, bring thought and people together rather than divide them. These universal ideas or the search for them create the possibility for a coherent vision on which to base a philosophy and practice.

In all three cases, these deep level ideas, simple in themselves are nevertheless hard to demonstrate. As for proof, for now they must remain elusive paradigms, ideals, questions of faith. There also appears to be an increase in fragmentation regarding the nature of uniformity. By this I mean that scientific philosophy requires there to be what is known as the doctrine of uniformitarianism applying to all branches of science and technology. The doctrine remains the same for all practitioners whether one is talking about medicine, chemistry, biology or physics. 1 With religion on the other hand, the nature of uniformity can change according to belief. The divine agency and its effects differ or agree from one religion to another. The plurality is directly proportional to the number of practitioners that adhere to one particular belief or another. When it comes to art, the situation becomes even more fragmented. The variety and number of different paradigms is a function of the countless movements, groups and individual artists that work and have worked to a particular vision across all societies. 

In science, there is a constant search for the consistency of the laws of the universe or perhaps better put, for any inconsistencies that might be observed which in turn, could lead to revised, refuted or new theories which would nevertheless still be based on the assumption of universal uniformity. The spiritual believer is ever racked with doubt about the justice of things, questioning the purpose or reason for the world behaving as it does; asking why justice, redemption and even punishment take the shape they do. Recourse is made to faith in the divine as the pillar on which the belief structure is supported. And the artist has to be authentic in themselves, find what is at the core of their being in order to make sense of things and synthesise them into something that creates a commons with others.

 

 

Uncertainty, Time and Distance

Each one of these persons must trust in a different kind of uniformity but this is not static. It is a concept implicitly embedded in the idea of change. The implication being that the same change would occur under the same conditions wherever and whenever they occur.  The key here is, under the same conditions. Conditions change and so do outcomes, but an outcome is not as a result of different laws acting. The outcome is the result of the same laws acting on a different ‘mix’ of elements. This means that the laws are reliable but not necessarily predictable. Quantum mechanics has shown us that the predictable world is an illusion created by the averaged sum of an inherently unstable and unpredictable fundamental substrate. However, reliability is the knowledge gained from experience and a belief in universal uniformality, including the unpredictable quantum microcosm.

When it comes to art the matter is somewhat more subtle because art is contextual. Context is an elusive characteristic of complex circumstances or conditions. At first sight, the ‘doctrine’ of uniformitarianism might appear to fall apart but this is an illusion. An illusion created on the surface of things due to context being a chaotic complex of influences and forces, relationships and interactions that provide ‘unique’ conditions resulting in the individuality of artistic visions and production. However, there is no reason why the forces acting on each and every artist are not the same, only altered by circumstance, genetic and cultural predisposition, historical antecedents and so on. The outcomes may differ due to different causes but the underlying laws remain invariant. The result is that although they may appear vastly different to us, there are commonalities which when averaged out produce the sum of human culture. And the wider the sweep of observation across societies and periods in history, the fewer the global correspondences giving rise to the difficulty in defining what art is. 

An example of outcomes being vastly different but the laws at work remaining the same, would be the existence of life. Life exists on Earth, no other life has been yet found anywhere else in the solar system. Yet, the abundant, exuberant ecology of our planet is subject to the same fundamental laws found anywhere else in space. The differences are due to local conditions and which laws apply or not and in what proportion. For example, life on Earth is very much dependent on the planet’s distance from the Sun, its magnetic field, age and so on. 

The interesting thing though, is that the fundamental laws acting on say, the Moon are the than those acting on Earth: yet nothing much changes on the Moon except for a few parameters, conditions are much simpler. The planet Venus on the other hand has a complex active surface, more complex than the Moon’s with an atmosphere and geological activity, yet it is much simpler than Earth’ surface. On Earth, once life emerged, perhaps as long ago as nearly four billion years, a different set of laws arose. A traversal takes place with the emergence of an ecology which in turn gives rise to evolutionary processes. New laws come into play, sub-laws which are nevertheless subject to the fundamental laws that existed before and continue to do so such as, the laws of thermodynamics. However, these new laws are also different in kind because they act on different kinds of systems such as living organisms (in which case reverse entropy). Could the same be said about consciousness, that once consciousness emerges, a new set of laws comes into action? 

Art is a product of our consciousness and part of human culture. Art emerges relatively late on in our evolution, it took some time for art, religion and science to emerge in human culture despite humans appearing in their modern form long before. Could there have been a hidden mutation that caused a leap in human activity, or was time needed for new proceeses to emerge out our consciousness and interactions with the world? And if so, are these processes subject to the same laws acting on new conditions or are the laws a new emergence from consciousness? Or put another way, are there correspondences between the processes that govern society and culture and those that govern other forms of life? If so what are they? If not, what is special about cultural laws?

My hunch is that there are correspondences, as stated by Dawkins in his idea of the cultural meme acting as a selfish gene; also, crudely put, Malthusian-like forces acting on how populations react to conditions. Research into free will is throwing light on how free we actual are, whether it is an illusion or partial illusion and what the forces are that act on us to make us behave and perceive in a certain way. But my intuition also tells me that there are some elements of human activity that have produced unique rules. Whether these are inherent in the domain, such as mathematics and aesthetics or universal and stand outside the need for human presence, is a matter of constant debate.

For the very reason that uniformity is masked by differences in local conditions, the forces at work are often not self evident. They would go against experience and be counterintuitive. To begin to understand them requires prior knowledge or experience, at least familiarity with the field. You cannot understand a scientific theory without the antecedent knowledge that goes to make it up. In a similar way, to understand or appreciate a ‘piece of art’ an experience connecting one with it in some way helps. Whether it be by association, familiarity or knowledge of the field, as Dewey might have said, context creates the artwork in the receiver’s mind. 

Perhaps these are intuitive thoughts trying to deal with counterintuitive ideas, such as probability (which is why quantum mechanics is such a difficult field to grasp and accept)… and certain forms of art. But why does art produce such strong emotions when debated? Art in particular divides opinion far beyond its apparent effect on everyday life with opinions being expressed in ways they would not about other matters even to the point of causing offence more readily than in other situations. I think that the effect of art runs much deeper than one might realise. People in power or seeking power have known this since early times. Art can be used to mould opinions, beliefs and allegiances from politics to economics, from status and fashion to the expression of wealth, social and philosophical ideals. Art can even persuade people to be kind, generous and cooperative or cruel and violent. Art is at the root of religion, fashion, status, politics, all complex human activity. Whether it is a simple bead necklace from the Kalahari or Michelangelo’s Pietá, whether a feature film or Homer’s Iliad, they are all expressions of human interactions between themselves and the world. The anthropologist R. L. Anderson suggests that art is:

culturally significant meaning, skilfully encoded in an affective, sensuous medium.

A Reminder When Writing

 

 

I came across this rather irreverent table yesterday. It is aimed at the authors of science papers but I think it can equally apply to the arts if clear thinking is considered a desirable thing in this field. I can say that I have been guilty of writing bullshit at times. That is why I constantly need to remind myself against doing so. When writing I ask myself a number of questions:

  • Do I understand what I am dealing with?
  • Do I have the means by which to speak of it?
  • Am I aware of the holes and caveats in my own argument?
  • Am I using a fallacy to support an argument? For example, begging the question or using the conclusion as the premise: all too easily done. 
  • Am I trying to be objective or subjective? Which ever might be the case, I need to make clear my stand point; observation and opinion are two very different things. 

But, I must also remember that I should not be afraid to make mistakes, take risks and make intuitive leaps. The absurd can be a useful tool to highlight an issue. 

The logical, the heuristic and the intuitive may seem at odds here, and on the surface they often are. However, artistic practice is far more complex a process for one to be constrained to rules adhering to a particular paradigm. Like the whole of life itself, to question is to remain open and live to the world, and one’s art practice is a personal reflection of the world lived. Being an artist, particularly today, provides one with the privilege of stating the speculative, imaginative, daring and singular, the uncomfortable truth and the lie, promote change and be dangerous or liberating, perhaps at one and the same time. It is about making a personal statement that if sincerely and honestly stated, being authentic, it is possible to make a wider statement that speaks for and to more than one person and is communicable. I can only deal with a small area of a vast world case. To attempt otherwise would be to assume that one can understand the entirety of things.

I try not to obfuscate in my writing although at times, for the sake of brevity I must make assumptions and express myself in a form of shorthand which may need unpacking: a necessary avoidance of overly long posts at the expense of time spent making. Returning to the original point about writing, I think it apt to finish with this cartoon that makes the point in a humorous way:

 

 

Stand the monologue on its head and one comes nearer to the truth. 

I now have to be careful to live by this…

…and take risks at the same time.

So long as I am aware of what I am doing I hope to avoid unintentional bullshit.

 

Mea Culpa Leads to a Unification

 

 

This piece was the one that exploded in the kiln and caused the damage. I am now reaching the end of its reconstruction and there are two more well on their way. This small project is running parallel to the main project proposal. It is a reconnection with clay and the organic. However, it is not a caprice, as I reflect on what I am doing, pertinent ideas come to mind: composites, contingency, deep past and cultural transitions, modular thinking, dialysis and synthesis, destruction and construction. The list is endless and endlessly layered. What might be the locus of the Research Paper begins to come into view.

What is emerging is a synthesis of ideas that have so far only existed as a coherent ensemble by virtue of my imaginings and feelings that they are in some way connected. I also begin to see how they relate to present day concerns in articulable form.

Patterns exist at all levels and scales of existence, repeating cyclically, each iteration different but nonetheless containing within itself a core that binds them together. Contingent events can cause large ruptures in systems, nothing is certain or inevitable but seen with hindsight, they appear inevitable and progressive, even predestined. This latter fallacy is a function of how we think, as though things have an aim or purpose. Algorithms are dispassionate and impartial. Disparate life processes, their repeating patterns throughout the planet’s history and from early civilisations to today’s society all bear the imprint of algorithms that might provide one with a glimpse of the future. But this vision cannot be discerned in detail but rather a direction of travel, subject to contingent events, the unpredictable.

What I am sensing is the repetition of patterns within patterns, fractals of fractals; that the history of life, human culture, and the future, are iterations subject to principles that become evident in different ways according to circumstance. The word I have identified as emblematic of what I might explore in the R.S. is metamorphosis. But this does not tell the whole story. Things come together to form more complex, sometimes simpler more efficient systems. Whether they be societies, organisms or ideas. All these things are subject to common laws, the same principles that defy entropy and sometimes succumb to it. Another word close to metamorphosis is emergence, the result of a traversal, a change in kind as from simple chemical reactions to ‘self interested’ replicating molecules or at a higher level of complexity, from sentience to consciousness.

The whole is not made of separate things but we perceive it as such by our own modularity in thinking which in turn could be postulated to be reflection of how consciousness emerged from simpler, chaotic but ordered, causal processes. Time is the function of such changes. We measure time by the rate of change in things whether while looking at a second hand moving across a clock face or our own faces in the mirror as we age. However, time is a flexible construct. It is not uniform or fixed in the physical world; the mind is inconsistent in how it perceives time. The notion of time of itself is meaningless.

But what on earth am I talking about? Whether I am talking about societies, organisms, consciousness or an artwork, the way these things are built is piece by piece, each component interacting with other components in reciprocal feedback relationships. Components group to form units at a higher level of organisation. Levels ‘talk’ across boundaries of complexity and with the outside world. It is a wondrous web of regulated processes of ‘communication’, regulated if that term can be used, by blind, impartial algorithms. Daniel Dennett talks about the nature of algorithms at length in his book, Darwin’s Dangerous Idea. By their very nature, algorithms are independent of substrate which means they can apply to different systems whether chemical, physical, biological, ecological, linguistic or cultural.

I am seeing how what happened during the Cambrian explosion as an analogue to the rise of complex urban societies: new ecologies, innovative strategies all based on modularity. The modularity of body plans and their genetic control and modularity of thinking fostered by the coming together of disparate modes of living encoded in art, religion and writing respectively. And if one looks close enough one might see a common thread made evident in the evolution or building of new blueprints whether they be organic or behavioural. And the drive for these changes may differ, whether it is an increase in oxygen levels in the atmosphere hundreds of millions of years ago, the increase in meat eating (and therefore scarce fat) helping an increase in brain activity many tens of thousands of years ago or more recently the retreat of glaciers a mere twelve thousand years ago. Changes in the environment give rise to changes in life: a thought well worth pondering on with respect to human induced climate change in the Anthropocene.

Can equivalences be made between world events? Can we infer sufficiently accurately to postulate what might happen in the future given certain conditions? And what of contingent events, is human unpredictability that difficult to allow for or are there only a few variables on a large scale? The scale at which something is looked at can alter conclusions. It is hard to predict the behaviour of one single item in the midst of the countless, but the whole will follow a pattern much easier to understand. What is the link between the two, between the individual and the collective? 

Our ability to alter the planet surface gives us power over our future but can we learn from the past to avoid the inevitable or are we condemned to repeat a pattern which, while different in broad details, is the same at a higher level? This may be where the digital revolution might have a decisive role for the better or the worst. If we want a degree of stability, we cannot leave the future to the contingencies of human behaviour. But is human behaviour contingent or predictable? It seems more and more the case that it is the latter but does this reconcile with individual freedom, if such a thing actually exists? To what extent are we free to decide as individuals and more importantly as collectives? Is it enough to say that the collective is made up of countless individuals or is some new paradigm needed? How dangerous could this be? Social engineering is not a new thing.

 

Action Research and Reflection: Jonathan Kearney Lecture

Note to self – watch the video again, before reading once more what I have written. This is not a regurgitant of content, it is a spontaneous assimilation awaiting future reflection. So watch the video from time to time even if I think I already know what it says.     www.bitly.com/MA-youtube2018-19

This lecture is an excellent exposition on methodology and how not to suffocate with dogma, prejudice, lack of direction, inappropriate and imposed expectations: to be all you can be as an individual amongst individuals. But to have it so clearly and concisely laid out belies the time and thought that has gone into such a simple explication. It brings together complex aspects of creative thinking without even touching the medium used or the work itself. This deft handling of practice methodology leaves matters open and flexible. It is not a prescriptive way or approach but a practical philosophy based on experience, knowledge and research. I feel very at home with the ideas and to have them put across in such a clear and simple way helps me identify where and how I can improve on my thinking or better said, how I can avoid wrong thinking.

But avoiding wrong thinking is not the same as avoiding mistakes. Mistakes are part of the learning process and the finessing of a craft. It is necessary to make a mistake to know what not to do. This may appear counterintuitive but to aim for the ‘right’ or correct thing, to have a set paradigm, often leads to wrong thinking. Wrong thinking starts out as knowing exactly where it is going and as it starts to loose its way, asserts its stance with greater force, but it is only heading towards a mirage. This is a cycle in which learning is reduced and can only lead to frustration. Mastery is the removing of veils, it is a reduction to the core of something. It is not about making it right but avoiding mistakes once made: knowing what not to do. 

I have often wondered what action research is. It is the everyday process that an artist engages in. It is to focus from within what is being done regardless of the esternal world. Perhaps this is what is meant by the much abused term, art for art’s sake. It is a cyclical process that never ends, where learning never ends, and that is exciting. 

Reflecting on reflection: at the start of these two years, three weeks ago, I stated in my first Project Proposal draft, that I was looking for the connective tissue in my practice. What is starting to appear is a picture where writing links the various means and outcomes I am involved in. This journal is beginning to create a framework. I have so many things to write about in relation to my practice, ideas, experiences. I am excited to see how the framework emerges, a body constructed with the elements of my practice acting as organs, limbs and manifestations of the whole. After all, what Jonathan talks about in the lecture is about knitting together a holistic dynamic process of integration, accretion, assimilation, and making it your own. Where this might lead is an open question that will only be resolved later along the course of these two years; even then the process does not end but starts, again. It is not something that cannot be hurried, only intensified. 

Jonathan also talks about the idea of reflection on and in-action. To reflect in-action is so much easier if you are already practiced at what you are reflecting on. When learning something new, I aim to understand, then do and finally, usually after a pause during which assimilation takes place, I can fully immerse myself in the activity so that I can step outside the doing while being in the action and reflect as it is done. This process is one of detachment and integration at one and the same time. I become one with what I do and also aim to be able to explain what is being done. That is why simplicity is essential. If the matter in hand is made complicated or appears complicated (makes no difference), reflection in-action becomes thwarted. This is why practice is so important. Practice makes something ‘automatic’. However, there is something about practice that is little understood. Practice does not of itself make perfect. Practice makes permanent. That is the reason why it is more important to know and focus on what not to do rather than on striving towards a paradigm.

[I have to say that since I started this journal, writing has become easier and each piece of writing takes less labour. But I still have to focus equally; it is just that it comes more easily and takes less time.]

Jonathan’s list of what to keep a record of in the blog journal is worth revisiting regularly:

  • actions
  • decisions
  • thought processes
  • successes and failures
  • issues you are dealing with 

The lecture also covers the difference between art and science research. Science is what I started with. I loved the themes and ideas but to have done research was not for me. Science is a victim of its own success. It is constrained by the scientific method. This can be summarised as the need for repeatability, falsification and personal detachment. It is the antithesis of artistic practice which emphasises individuality, uniqueness (which is very different to originality) and verification. Scientific ideas are universal, open to appropriation and waiting to be shown as false. Art is personal and subjective, it is also universal.

I am a metaphorical being seeing the world and explaining it in terms of labels: that is how language works. Language is the basis for reasoned thought. Whereas science looks to tropes as ways of explaining and understanding but always with caveats, art embraces metaphor and other tropes as means of opening out to nuance and subjective communication and of asking questions. I wanted to be nuanced and have the possibility of portraying ambivalence and ambiguity in my work, speculate and imagine. That is why I did not continue with science. I still attempt to be logical but not as a reductive, deductive mechanism for inference. The logic of what I do is often hidden in the weave and texture of the work and reflection is part of teasing it out and making it more apparent to myself, to start with. This is a principle aim of my MA research. It is a matter of constructing a valid argument but not necessarily a sound one. The reason for a sound argument not being desirable or even possible lies in the very way art practice evolves. By every definition that contains humanity at its core, art is subjective. A non-false premise, for that is what a sound logical argument must have, need be objective. Therein lies the point of potential conflict in any artistic discussion. Validity and soundness of argument are two very different things. To believe in the soundness of an artistic argument is a false notion and requires as back up falling into dogma and faith, something that an artist might well have difficulty in contending with if they are to maintain openness and follow a holistic approach. 

An interesting proposal nearing the end of the lecture was that science leads to no change in the world whereas art does. This opens up a whole new and long discussion but I would like to finish off by reminding myself that science is not technology. Science is about finding explanations for how the world is. Technology applies these but it also applies social, economic and other non-science based ideas. Technos comes from the word techne which although closely related to the meaning of episteme (knowledge and understanding), it emphasises active application of knowledge. Whereas science is about understanding, technology is about applying understanding. Both techne and ars refer more to human activity than disembodied knowledge. Note that this disembodiment of knowledge becomes a universal idea that can be appropriated by anyone whereas technology and art very much bear the stamp of authorship. This is embodied in the concept of copyright, you can copyright a means of doing something and an artwork but you cannot copyright an idea.
