Show HN: Simple way to generate music with cellular automatons

At Toronto Music Hack Day I built a simple, yet sleek grid based interface to generate music with cellular automatons. Tap on the grid to add more atoms.

It's rather beautiful as although the music is random sounding, it's actually 100% deterministic.

I made a web version and an iPad app. You can also share the state of the grid and share it via link:
