Over on Create Digital Music I was reading about an interesting new app where you shake your phone to get a free album. Unfortunately it was rejected by Apple as being "useless". From the trailer for the app it seems as though you shake to hear the music and then, like with a hand cranked turntable, it eventually starts to slow down until you shake it again to get the speed back up. If you do this well enough you're rewarded with the artists album to listen to at your pleasure.

I'd hope that this isn't the full story and that there was some other reason for why the app was rejected but Apple are a strange bunch.
