Nano Copters

I imagine this video is going viral to some degree by now. First thing I though of was how CGI and movies could harness these things to create even more realistic flight sequences like in Star Wars for example. I particularly like how the one copter can flip. I started imagining our own flying saucers one day. Or...one night, as a prank, these guys head for farm country, hook LED lights up and fly over Old MacDonald's farm and generate some UFO sightings? Cool and fun!
