AUUG Motion Synth, IPhone based motion sensitive Midi Controller

I'm pretty excited about this Kickstarter Project: http://www.kickstarter.com/projects/...ent-into-music

We have seen a lot of motion based MIDI controller designs, but this one strikes me as the most useful so far. I can see a lot of fun applications for life performance routines in this one, as the amount of control seems to be pretty fine grained. What do you guys think? It's a bummer they don't have their left hand design up yet, would be pretty epic to have one of them in each hand and control two instruments at the same time during a life performance. Can't wait to try this out. I hope their Kickstarter comes through. But it looks pretty good, only about 3500 left and 6 more days to go. Crossing my fingers.
