A theremin is a musical instrument1 that you play without touching. Two antennas pick up the movements of your hands, and translate them into pitch and volume. They rock. They’re also quite expensive. They’re on my Things To Own In An Ideal World list, sandwiched between an armonica and a trichobezoar. None of these are likely to happen any time soon.
Except, I might have a chance at a theremin, as someone has built one from a wiimote. I MUST DO THIS.
Gotta get a Wii first, mind.

I saw a theremin a few years ago at a Simon & Garfunkel concert. It was pretty nifty. I remember thinking “Holy crap! A theremin!”
Also - fun random bit of trivia - in “Hannibal,” Hannibal Lecter has a theremin. Actually, that’s how I first learned about theremins. (Not sure if it was in the movies, though.)
I’ve hooked up my laptop to the local Wiimotes, and it’s very nice. Brian Peek’s C# wrapper is pretty easy to code for, and I’ve already made the Guitar Hero III controller play music. I did consider having a go at a theremin-like thing but never got round to it. I’m glad someone did.
I really have to get hold of some IR LEDs. I have no idea where one gets those from.
