Drones are getting smaller and smarter

The Aerius is so wee, you'll probably be afraid of losing it or poking someone's eye out. But look how adorable it is! Claiming to be the world's smallest quadcopter, the Aerius from Aerix Drones is 3 centimeter across and comes with a controller that doubles as a case. This guy can also do flips and show off with flashy lights.
