This is an awesome video showing group control through networking. The flight characteristics of the nano copters shown early in the video are pretty cool. The ability to right themselves, return to a position they are launched from, and do mid air flips are all impressive. But I think we can all agree that the synchronized action is what made this video so popular.
Not to be outdone, here are some Japanese students doing some synchronization of their own. It’s a long video, but watching the area around 1:30 seconds in is pretty impressive.
