The French company Parrot has made a model quadracopter that includes a built in WiFi network so that it can be controlled by an iPad. The model has 2 video cameras that send real time video back to the iPad's display.
The app that controls the quadracopter features augmented reality which places computer generated images in the real time video feed that is sent back to the iPad. This allows the end user to play video games in any surroundings that they can travel to.
