An early, serious abstract animation composed solely of squares and rectangles that change shape. Another attempt to apply musical principles to screen images.
Richter wrote of his own attitude toward film: "I conceive of the film as a modern art form particularly interesting to the sense of sight. Painting has its own peculiar problems and specific sensations, and so has the film. But there are also problems in which the dividing line is obliterated, or where the two infringe upon each other. More especially, the cinema can fulfill certain promises made by the ancient arts, in the realization of which painting and film become close neighbors and work together."
