I was web surfing and found this:
http://www.audiovisualizers.com/toolshak/vidsynth/djones/djones.htmI worked with Dave Jones in the seventies at the ETC. The picture in
the upper right corner shows Dave using one of the audio synths I built
for the ETC (two yellow boxes) to control his video synthesizer (the
white box), which was made for voltage control. To the left, just above
Dave's shoulder, you can make out some yellow and brown equipment in
racks. That is some of the video synthesis equipment I had built.
