Brilliant!
Another hit magic app! Just be sure if you are performing this trick in an atmosphere with little ambient noise that as part of your performance you are talking or making "mind straining" noises to mask the sound of the vibration as the phone spins. The sound is very quiet so if you are in any public place (which is usually the best place to show off this app!) you cannot hear the vibration over normal ambient noise.
