I'm sure that somewhere in a mad-lab somebody is already working on that iTit thingy...
probably the same guys that developed the iPod Vibrator, which vibrates in the rythm of the song playing.

It comes with a cable splitter, so you can use your headphones to listen to the music that's "playing". Or you can combine it with iHome, which got a wake-up function (alarm clock).... imagin the possibilities!!!
