Control the wondrous spinning-frog game of Zuma's Revenge with a rotating chair and an Airzooka. Maps compass rotation, flex sensor and push button input to USB actions to control Zuma's Revenge (http://www.popcap.com/games/zumas-revenge/online)
Dependencies: LSM303DLHC mbed
Note that content for USB HID and USB Device is actually from the USBDevice mbed library. However, we made a couple of small changes to this library (allowing USB clicks at a particular location) that required us to break it off from the main project if we wanted to publish without pushing upstream.
