iWatch Metronome

I wanted to play with a concept of using the accelerometer on the iWatch, as well as pinch-and-zoom to increase the beats per minute. Options would include up/down rhythm, sound on or off. The graphic in the middle would pulse with the beat and use haptic feedback for the user. I could see this being worn on the wrist while playing a string instrument, or set on the edge of a table while playing a ukulele or piano.
