I used to be pretty good at programming my Commodore 64 computer and I wrote a "light show" program for it that I used onstage. Each function key would trigger a different light pattern and I had the computer plugged into a VCR with about 6 video monitors placed around the stage.

In the band I was in at the time, that was my job. I was The Onstage Light Show Guy. I would just stand up there, poking keys. People in the audience didn't have a clue what I was doing up there. They thought I was playing music. It was a ton of fun.
