Vapor trails. Art is the particle and I am the cloud chamber.
In a cloud chamber, we cannot "see" the particles - whatever they are called - mesons, pions, peons ... some are too short-lived for any hope of being seen ... but we have evidence that they are there by the effect they have in the surrounding atmosphere in the cloud chamber - they leave vapor trails.
So it is with me. I can't consciously "see" art - but I know that it exists, by its effect - the "vapor trails" left on my "being".
So that good feeling we get when we shoot or print is a vapor trail? That would make sense. After all, the feeling itself doesn't exist (materialy). Its all chemical signals in the brain.
