One surface will be painted with fluorescent paint. In front of the surface, six camera flash lights connected to six motion sensors will be placed. As people walk through, they will trigger the sensors and a flash light will be shot. In this way the shadows of the pedestrians will be projected onto the wall. The fluorescent paint will capture the silhouettes of the pedestrians and will show them for a moment. The shadows will be presented in black "frames". This technique turns the wall into a giant photographic film, that registers different scenes from the urban life. The project creates a playful space where unkown persons can interact, improving the quality of the urban life.
