Wolfram Tones - Sound Generator using Cellular Automation

While investigating the latest search engine craze - Wolfram|Alpha I discovered another of Wolfram Research Labs projects called WolframTones.

According to Wolfram Research Labs:

WolframTones works by taking simple programs from Wolfram's computational universe, and using music theory and Mathematica algorithms to render them as music. Each program in effect defines a virtual world, with its own special story--and WolframTones captures it as a musical composition.

The tunes generated can be saved as MIDI files to be used on mobile phones. Try it out!
