3D Balls app for iPhone and iPad

3D Balls is a three dimensional simulation on your iPhone of multi-colored balls bouncing around in a box. The application creates an illusion of three dimensional motion as they move up, down, left, and right as well as back and forth. The balls collide with each other and the walls in a realistic physical simulation.
The application responds in real time, through the accelerometer, to the motion of the iPhone, allowing the user to move and shake the balls by moving and turning the iPhone. With 3D Balls, users can entertain themselves by bouncing balls, wherever they may be.
