GraceGrader -- App that grades how graceful you are. Correlate this with other factors about a person. Maybe could even be used for marketing/healthcare. Could be done with iphone or even webcam/computer (webcam sees if your head stays level or jerks up and down).  Maybe could even tell if you slam the keys too hard using sound data (and speed data)!.
