Best Theremin Video on the Net

Here.

Starts with woo-woo noises, launches into demo/humor, motors through a circuit diagram, and finishes with a beautiful rendition of Ave Maria.

That's a really nice Theremin, wish I could identify the model.  Good effects processing too.  Nothing over-blown, but a good complement to the instrument.

Gonna go practice now.  My eventual goal: to competently play Free Bird.
