redUniform - wireless hardware

I have constructed a wireless sensor system for my performance costume. It has 2 accelerometers (3-axis ADXL330, SparkFun - same as in the Wii remote I believe) and 4 switches (digital). Both master and slave uses a microcontroller (ATmega8, Atmel) and a transceiver (Mirf v2, SparkFun).
Below is a short video, some pictures, SuperCollider classes and also the schematics and the complete firmware if you want to build the thing yourself.
