Robotic hand plays piano classics

From Beetoven to Scott Joplin, on AA batteries

Robot piano hand

It's a graphic example of the convergence of music and technology, with a bit of Halloween creepiness thrown in for good measure. This robotic hand, according to Book of Joe, mimicks the playing of six piano classics, including Beethoven's "Fifth Symphony", Scott Joplin's "The Entertainer," and Chopin's "Minute Waltz." Sound sensors start the device when you clap--not quite the same as raising a baton, but close enough for a musician that runs on AA batteries.
