This device is way cooler than its official description may lead you to believe: "Media artist Toshio Iwai and Yamaha have collaborated to design a new digital musical instrument for the 21st century, TENORI-ON. A 16x16 matrix of LED switches allows everyone to play music intuitively, creating a "visible music" interface." Available only in UK so far, but not even there at the moment since its out of stock.
See the device in action on YouTube.
