This is pretty cool, occured 3wks ago in Germany. It's not DJI, but still a very cool accomplishment, 100 drones, at night, to live music from an orchestra playing Beethoven’s Fifth Symphony. It's apparently sponsored by Intel, who's in bed with Yuneec (recent $65mil investment), but these are not Yuneec drones either.
