One of my favorite phenomenon in slinging glass(picture taking), is subconscious attraction. I note something, move toward it, put an eye on it, take it, and ask later. This happens to all of us daily. We are motivated by these underlying predilections, based on memories maybe? Memories we don't remember? Imagine how much passes before us that we don't register-- but is still in there. Why do I move toward a burning chair? Is it a dream?
