English: An interactive sound and light installation by Dutch media artist Edwin van der Heide. In a room, a row of dim quartz lamp lights is positioned on the wall, approximately one meter high. The visitor receives a box with a sensor and a pair of headphones attached to it. Using this apparatus, the visitor can approach the lamps; light rays are translated into sound frequencies and the intensity of the sound is dependent on how close or far away the sensor is from the lamps. Each lamp is connected to a different sound, and moving between lights creates a combination of the two different frequencies. The audio is reminiscent of science fiction sound effects from the 1950s and 60s. As the lamps only produce around 50Hz, the room is illuminated with a soft and comforting glow.
