the concrete jungle
"At night projections from moving cars are shone on the buildings downtown. Each car projects a video of a wild animal. The animal’s movements are programmed to correspond to the speed of the car: as the car moves, the animal runs along it speeding up and slowing down with the car, as the car stops, the animal stops also. The framerate of the movie corresponds to the speed of the wheel rotation, picked up by a sensor."
