On the side, I used to do lighting for some of the underground clubs in Los Angeles (long before they were ever called raves, late 1980's to early 1990's) and we always had a "chill" room set up with the oil wheels. I didn't own one, but did have beamer lights, lasers (both green and red), smoke machines, strobes, black lights, rope lights, etc., etc.! Fun times. ?
Heck, I was even written up in the High Times magazine about what a great job I did on one club called Altered States.
