Turing Completeness on the iPhone (aka a thing I built)

Hi all. I am unabashedly spamming, yes. I recently built an app that has a turing complete CA in it, and apparently this particular turing complete CA is on the right side of apples review policy. I got a little bit worried there for a second.

This is a sequencer and synthesizer that you can trigger with wireworld, a 4 state, 2d cellular automata that is pretty easy to build logic with. Hopefully someone gets a kick out of it.
