Didn't you all think by Christmas 2010 we would have robot butlers to fix us eggnog and buy our Christmas presents? We don't, but here's something cool: A flying robot that plays 'Jingle bells' on a keyboard.

The video was recorded at Switzerland's Flying Machine Arena, "a safe, controlled environment allowing the testing and validation of mobile robots." We're definitely putting one of these things on our Christmas list next year. [via Slashdot]
