Engineer Thomas Macrina set up an anarchic indie booth along one wall of the PAX East showfloor, behind a row of exhibits and under a pair of escalators, with three very hand-made signs. Still, he attracted our attention and a small crowd of curious players: Each person took turns holding Macrina's iPhone 5 as if snapping a MySpace profile photo, made a gun with one hand, held it to one cheek and went to town, snapping that thumb and rotating the phone around the room.
Macrina called it Pig Hunt, an augmented reality game for iOS devices. Think Duck Hunt, with your hand as the zapper and the world as your playground. Try not to smile.
