Battling AR helicopter controlled by iPhone

The new AR Drone helicopter combines an iPhone and virtual games to make a product that's drawing much attention at the Consumer Electronics Show in Las Vegas. The helicopter, or what France-based Parrot calls a quadricopter has four fans that allow it to fly in all directions. Under development for four years, the most impressive aspect of the AR Drone is that it streams real-time video from its two cameras back to the iPhone or iPod Touch that is controlling it. Tilting the iPhone to use its accelerometer controls the helicopter's flight.
