A cloud-like, 400-element sculpture, begun in 1983 for General Electric but never finished because the company abandoned, for budgetary reasons, the program with which it was to be associated.  The cloud would be controlled by a computer, one whose task every morning would be to create the script for the day.  Each element could be raised or lowered to occupy an exact position in the matrix.  Each element incorporated a light that could glow at 16 levels of intensity and a tuned musical ring that could be struck at an exact time and with a determined forced.  Many chance and nonchance elements would determine the choreography of the parts, the play of the lights, and the musical use of the rings.  The rings were to be tuned in quarter tones to ring from the C# above middle C up to the next C#, 25 tones in all.
