I found this on the web a couple of weeks ago, it's a proximity sensor that works quite like a Theremin, and that provides a current flow instead of a sound, so you can use it as a CV controller for a synth, or any FX pedal using a Vactrol optoisolator..

I'm building one of these, almost complete, to make a Theremin-like MIDI controller.
