I have hacked together a Chronos watch demo that adds some technological fun to the Labryinth ball maze. The demo uses a Chronos watch and a Stellaris DK-LM3S9b96 dev board.
The chronos watch sends accelerometer data to the DK-LM3s9B96 via the 900mhz link between the watch and the board utilizing TI's Simpliciti RF protocal. I removed the knobs on the game and replaced them with gears.
I added some RC servors that are being PWM driven by the LM3S9B96. The servo position is based on the accelerometer data that is recieved from the watch. As you tilt the watch, the table tilts with it.
As the watch is being moved around, a graphical representation of the accelerometer data is drawn onto the display attached to the LM3S9B96.
Here is a video clip:
