Cellphone piano fulfills the full range of our childhood fantasies
 

Each key on the piano is wired to a key on a phone, and while we haven't heard it in action, this contraption is sure to produce the most beautiful noise known to man -- or at least since your older brother figured out "Twinkle Twinkle Little Star" on the touchtone in middle school. If only Chopin had technology like this at his disposal back in the day.
