Ink & Switch are having a hack week, and I'm working on a generative sound project. You can check out the current version (likely to change as the week progresses) here:

It sounds a little different every time you run it, but it's also synced to the system clock. So if you run it on, say, every device you own and scatter them around the room, it creates a rather neat immersive aural space.
Would appreciate any bug reports, especially on Android!
