Seems like everyone is trying to scale up the game of Pac-Man lately. Enter Pac-Lan, a game where players keep tabs on each other with their cellphones while physically playing Pac-Man in costumes and all. Created by researchers at Lancaster University's Department of Communication Systems, each phone has a pre-programmed map based on the university's campus. The players have to run around to yellow dots stuck on lightposts that are actually RFID tags that beam the player points. Everytime a player collects a point, his or her location shows up on everyone else's map—that way the people playing as ghosts can come and try to chomp down on the Pac. Next up, the New York City MTA will announce that the subway system is being remodeled as a citywide Pac-Man maze.
