Pingar

Pingar is an Augmented Reality application that creates the illusion of playing a game of table tennis in the real world. Use your device as a virtual bat and touch the ball to make it go in another direction.

In singleplayer mode, the player faces of against a bot. In multiplayer mode you can play against someone else using the Pingar app in your location. Both players will see the same virtual scene in the same place in the real world.
