Wally Bally is a basic game for MacBooks. It uses the accelerometer motion censors allowing you to physically tilt your MacBook and bounce a ball. The objective of the game is to hit the walls whenever they are green to get points. Hitting a red wall results in loosing one of three lives.
FREDERIC TREMBLAY This application is really cool. It looks like it is still in the early stage of development (no icon, etc), but the main idea of using the built-in motion sensor is what makes this awesome. (Version 1.0)
