I make percussion-based electronic music with my hands. It's all 100% improvised on the spot in one do-or-be-terrible take.
2009 finds me improvising with a purple Zendrum and a couple of MIDI controllers. My stuff is percussive electronic improvisation (drums, timbales, congas, bongos, daixa, bàtás, brake drums, hang drums, etc.). If you don't like it now, check back in a few months: it's getting better all the time.
