Mentation (noun) - "the process of using your mind to consider something carefully; the process or result of mental activity". Documentation (noun) - "material that provides official information or evidence or that serves as a record." "Form is Emptiness and Emptiness is Form. Therefore, Form is not other than Emptiness and Emptiness is not other than Form. The same is true of Feelings, Perceptions, Mental Formations, and Consciousness." - The Heart Sutra, from Zen Buddhist writings.  Why, when, where and how does mentation start and end? Can mentation occur without an object to observe - can the observed object be an object of nothingness, and at that point - does the object become the subject (the human mind - the 'who' that is observing)? Can sensing technologies (the camera and a strobe light in this case, electron particle accelerators in other cases) enhance or detract from this process? Is mediated mentation through a piece of technology still mentation? That's to ask, would this art piece exist without a spectator to see it? Would 'reality' exist if there were no one there to observe it? Might one's notion of reality be the outcome of a coherent mental contruction, made by the collective Mind? As it seems there is a speculative start and end to the process of mentation, Docu-mentation intends to evoke such questions of perception. Only the observer can provide their subjective answers through their direct experience of reality. "The human observer constitutes the final link in the chain of observational processes, and the properties of any atomic object can only be understood in terms of the object's interaction with the observer. This means that the classical ideal of objective description of nature is no longer valid. The Cartesian partition between the I and the world, between the observer and the observed, cannot be made when dealing with atomic matter. In quantum physics, we can never speak about nature without, at the same time, speaking about ourselves" - The Tao of Physics, Fritjof Capra
