This is a video made by Donovan Drummond. The music is Morton Subotnick's Silver Apples of the Moon performed on the Buchla synthesizer. Drummond's LightsOut! light shows remind me of Glen McKay's Headlights liquid light shows from the 1960's.

I did a very similar rear projection light show once in the sixties using several projectors for a stage play based on Whitman's sing the body electric. Live dancers, vocalists and musician performed in front of a translucent scrim. We only had the theatre for a single performance.
