Turn an iPhone Into a Pocket Theremin

Earyauteur writes "The Unofficial Apple Weblog (TUAW) is running a story on an interesting motion-controlled iPhone application which uses the iPhone's 3-axis accelerometer to control a digital synthesizer. The musical instrument is played much like a theremin with the added ability to perform music using different musical scales. TUAW also links to a YouTube video which shows a performer demonstrating the iPhone instrument."
