langsound has been doing a lot of interesting musical experiments on his YouTube channel, but this one is quite clever! He's got his iPhone strapped up to an upended chair with rubber bands, and TouchOSC sending accelerometer data as MIDI to Ableton Live.
Now when his iPhone wobbles, his FM Bass synth wobbles with it! The actual bass patch isn't very good, but the principle is great!
I wanted to turn the iPhone into more than a little square that you hold in your hand. by adding the rubber bands, I could make different gestures (two handed gestures). ...steering wheel looking things. I then thought it would be cool to to be able to do some of the usual one handed gestures like changing things on the touch screen.
So flipped a chair over and suspended the iPhone from its legs. This took seemingly no time at all to go from usual tilting gesture, to making wobble bass, with something that wobbled...
