I was browsing youtube and I came across this video of the AR Drone Helicopter, it is controlled by an iPhone or iPod Touch (Wi-Fi) and uses the gyroscope for flight control.
This helicopter has two integrated camera's, one front-facing and one on the under-side. Both camera's are viewable on the iPhone/Touch during flying, allowing more precise flight without actually seeing the chopper.
It also has augmented reality games, using the cameras and helicopters actual flight.The AR. Drone is the first helicopter with automatic flight stabilization and is built for both indoor and outdoor use.
This helicopter retails for 299$ and has many other cool features I didn't mention. It is definitely worth checking out, I thought it was pretty wicked.
