Surf Google Earth -- Literally

Using the Google Earth application programming interface (API), a Google engineer was able to get the Balance Board to talk to the program after decoding the Bluetooth packets being sent from the board (that's how the device wirelessly interacts with a machine like the Nintendo Wii). The result (which you can see in the video below) allows users to move forward by leaning forward, move backwards by leaning back, etc.
