Android apps are written in Java and are pretty fun to work with.

You may remember me talking about a VFP app I recently wrote that leveraged the ChucK programming language?

I ported the whole app to Android (which didn't have a working ChucK implementation AFAIK, but had plenty of interesting developer tools and I borrowed some existing code and rewrote the features I needed). Here is the "Sketch-a-Tune" monadaphone I wrote in VFP ported to Android.
