Using open-source software, cellphones, and a mess of different wireless interenet tech, the students at Tisch School of the Arts made a real-life version of Pac-Man that was playable on the streets of Manhattan. With four players acting as ghosts and one as the pill-chomping champ himself, a group of off-site controller players would keep the players informed of each others' location via cell phone by tracking their location through custom software.
Pac-Man's goal was to flee as long as possible, but he had an edge thanks to his controller's bird's eye view of the whole game, including the coordinates of the ghost players. It kind of worked like a massive IRL version of Nintendo Land's minigame, Mario Chase.
