Like a laminar flow fountain? http://www.atlanticfountains.com/images/leap.avi http://www.atlanticfountains.com/laminar_primer.htm http://www.atlanticfountains.com/images/LoveFtn/HaveYouEverSeen.wmv I don't know anything about them. Good luck! --Winston

Is there a description or spec for your disco circuit somewhere? Grant.

I have three channels of state-variable type filters to sort which colors go with which frequency, and the "beat" is extracted via jam-locking a saw-tooth oscillator. I wouldn't call it "overly complex... but it is manufacturable, quite repeatable. > >Is there a description or spec for your disco circuit somewhere? > >Grant.
