Abstract

The present invention provides electronic visual display systems which operate on an input signal to provide visual outputs having patterns, colors and motions which may be varied in accordance with a predetermined scheme. The amplitude, tempo and frequency content of the input signals are used in a variety of logical selection functions to control the color, pattern and motion of lights in a visual display matrix having three dimensional properties in a manner influenced by the contents of programmed memory components. The memory component programming is sufficiently flexible to provide a variety of visual effects from the systems.
