VirtuBall

With a little more than one hundred straight lines and two circles the app gives you the three dimensional illusion of a cubic room, with a ball moving inside and two hovering paddles, one more in front, the other more in the rear side of the room. Steer the front side paddle by slightly panning and tilting your device and smash the ball past the rear paddle. The rear paddle is either steered by the included bot, or by an additional player connected wirh a second device via bluetooth.
