Hi,

I just came across this on YouTube and since I happened to have both a Big
Briar Theremin and a (Realistic) Plasma Light handy I thought I would give
it a try.  I play the theremin just below its lowest audio frequency to pick
up the sound from the plasma light which I touch with my other hand.  I am
amplifying it through a Fender Blues Jr. Tube Amp which I don't think
matters.  The plasma light sound is much quieter than the theremin sound.

Sorry for the off topic posting but I thought some of you would like to know
about this.
