Echo the piano playing quadrocopter gives us some Christmas cheer

If you've ever wondered just how controllable those quad-bladed r/c helicopters are, this video should dispel any reservations.

Performing at the Swiss Federal Institute of Technology's Institute for Dynamic Systems and Control, Echo the quadrocopter is programmed to pick out tunes on a regular basis by researcher Angela Schöllig, but this time she decided to endow Echo with a little seasonal spirit.

Watch to the end of the video for a blooper that shows what happens when things go wrong.
