In this elegant demonstration, Sandin explains the mistake of using common language concepts and spatial relations to describe what actually can happen on the video screen. The images generated in the tape act according to specific parameters set by the artist. Sandin has stated "The analog Image Processor was programmed to implement the logic equations; if square, if triangle and circle show circle." In this tape, Sandin is in effect arguing for a distinct video vocabulary that replaces the classical concept of perspective. This tape was produced at the University of Illinois Chicago.
