Tree Dancing	A desideratum of Dada and Rhythm Vision. Keep your eyes on trees and, as you pass by, allow them to rotate in your visual field. It is very simple but it opens the door to the mythopoeic imagination. Some trees are so provocative under these conditions that one must forcefully dismiss them with a "you brazen hussy" or some such verbal discharge lest they overpower one with their beauty. This principle can be extended to almost anything. I like dancing with the freight elevators in my office. They were painted Matisse blue and red. Now they are brown and gray, so I have to use more imagination.
The Crystal of Light	A term mentioned by artist Oskar Kokoschka to describe a painting technique used by Titian and Poussin. I have adapted it to apply to the rhythmic viewing of trees. In the early morning or evening or when the light is subdued, walking by a grove of trees (especially those with many small symmetrical branches) will produce a stroboscopic motion which seems to suffuse the trees with a sheer crystal of light. The same principle produces movies. Once this is firmly developed, one can see (or imagine) the crystal even when the strobe motion is not rapid or even when one is stationary.
