Nearly continuous color changes rotate around a spectrum, but this time at varying speeds of rotation and degrees of intensity. The colors on the left start white and rotate very slowly. As the film progresses the color values become darker and the speed of rotation increases until, by the end, the color is nearly black and rotates around the spectrum about once per second. On the right, the opposite occurs, starting black and progressing nearly to white. The film has an improvised electronic soundtrack by Richard Teitelbaum.
