Pop quiz: What's black and white, has 88 keys and makes beautiful music with Android? That'd be a piano -- and the new Android ADK. That's short for Accessory Development Kit, and it's the toolbox for the new set of open-source protocols that will let Android do new exciting things with just about any accessory imaginable.
And why not kick things off with some music? This setup from Miselu takes a piano and a MIDI controller and hooks it all up to a Motorola Xoom. You can manually play the piano via the Xoom, or just set the sucker on go and sit back and enjoy the party.
