At one time, when I played nite-clubs, I had one of those Christmas tree rotating disk lights that lit the wall behind me. The disk had three gels and it slowly rotated in front of a 100-watt bulb. After a decade, the disk motor died and I was never able to find a replacement or I would still have it today. It took up the same space as a 33-rpm record and weighed about the same as a record.
