Experiments in aesthetic.
Simple objects (like coins, pencils, leaves, flowers, tea bags, book) where rotated on my phonograph. The quality of the "paintbrush strokes", "paintbrush movements" and the amount of the blurness depended on the distance of the rotated object from the center of the phonographs plate, (near the center: less blur) and on the shutter speed that was used. (Higher speed: less blur).
