This... is... just... mindblowing.
It's a radio controlled 4 rotor helicopter, that you control using an ipad/iphone, and it has a video feed from the chopper back to your handheld.
What's more it adds extra bits and pieces to the video stream, so you can have races on a virtual 'racetrack', or play shoot em up games against virtual enemies, but with a real chopper flying in the real world.
(apparently the framerate has been improved in later versions of the software)
