This video of someone playing the Legend of Zelda theme on a theremin would've been amusing even if it didn't introduce me to the only instrument I know of that operates on the same principles of an RLC circuit.

Meanwhile, Gabe prefers this one, chirruping in time to it, and on pitch too. :-P

ETA: Oh, and if you can get me a better description of the physics behind the theramin, you get a virtual cookie!
