"Fire Organ was a program I discovered in the early '80s working at my father's computer store in Andover, MA (OnLine Computers, 2 Elm Sq. right across the the street from the library). At the time, I didn't realize that Fire Organ was actually a demo disk for a language called CEEMAC developed by Brooke Boering. I just enjoyed the seemingly endless permutations of the scores as they'd cycle through on the old Franklin Ace's or the Apple IIc's we had on display. I also thought it was cool that some of the music I had just started to get into (e.g. Pink Floyd) was mentioned in the liner notes as motivations for some of the scores. These were the forefathers of the visualizations made so popular by Winamp and other current audio players."
