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. | |
