Grant Richter's Wooglebug is based on the varactrol, or "hairball" component of course: (http://www.musicsynthesizer.com/Hairball/hairball.html) Plenty of things that could be done with this; a Universal Variable Junction using the common XY joystick as the control input w/ + or - 5vdc as the reference to the led or even a small incandescent bulb. But is it musical? Hmmm...
