I’m sure there are lots of reasons to get the cool AR. Drone by Parrot, but in case you need more – here is another one for you. The iOS AR. Pursuit multi-player game is an awesome way to get some 3D action.
Basically you’ll need an AR. Drone, an iPhone/iPod/iPad and the AR. Pursuit game installed on the iOS device. The friend you’re going to play against must have the same gear.
