People Pretzel is a computationally enhanced game board taht aims to encourage informal social interaction in public spaces. The People Pretzel uses sound, light and visual images to entice community members to participate in playful group interaction. To play, the players are required to collaborate, using their bodies as playing pieces. This physical interaction is computationally mediated and augmented to produce an improvisational multimedia performance for the enjoyment of players and spectators alike.
