Sean Dockray's PACK-MAN is a modified version of the classic arcade game PacMan, in which 5 joysticks combine (majority rule) to move the PacMan:
... if three people move their joysticks upand two people move theirs down, then PacMan will move up. If one person moves left and one person moves right, PacMan will do neither. The software remains essentially unchanged, although it runs much slower (to account for the speed of group decision-making) and graphics have been added across the bottom of the screen to communicate what each of the joysticks is doing at any given time.
