The Parrot AR Drone needs no introduction. If you don’t know already it has a camera that feeds video to your iPhone or iPad which can also be used to control the device. This makes it perfect for playful reconnoitering. For their demo at CES 2013, these four quad rotors were pre-programmed to do a dance showing off their precise flying capabilities. As you can see it was very entertaining, though I doubt four end users could match the performance given a lifetime of practice.
