Jestin Stoffel and Vince Thompson of the CCCKC have created a cool Wii Balance Board controlled Labyrinth Game which uses an Arduino microcontroller to handle some of the interface."Currently the game is using two servos and an Arduino to turn the knobs that move the game surface. I bought my Labyrinth game at a Tuesday Morning store for less than $10. The servos were about $10 each and my Arduino cost around $30. I often use the AdaFruit BoArduinos in the robotics workshops I teach which cost $17.50 so that could reduce the overall cost to build this project."Via: Nowhereelse
