Theremin is finally released on Android Market. It’s in alpha stage, but I will be updating it quite a lot. For now it might be used to produce sounds based on the magnetic field around your phone. You can manipulate it using a metal object such as a coin or your ear phones. It might serve as well as a metal detector!

There is a video showing Theremin in action.

I would really appreciate some feedback and feature requests. I hope you enjoy it.
