Watching digital graffiti on the faces of buildings is always a fun show to watch. Developers at the 2011 FÃªte des LumiÃ¨re festival decided to take the art form a step farther by creating an interactive pin ball show. The project is called Urban Flipper and it features a game that is projected onto the CÃ©lestins Theater and uses the buildingâ€™s windows, pillars, and other features as the gameâ€™s bumpers and other obstacles. A player controls the gameâ€™s flippers by pressing respective buttons at a control station. Between games, the display shows forests, vines, and even submerges the building under water.
