Artist Creates Sonic Graffiti [Video]
Benjamin Gaulon's light-to-sound device uses light sensors to create low-fi, synthesized noise.
Benjamin Gaulon, of Recyclism, has come up with the concept for an L.S.D. (light-to-sound) device, which ‘invites its users to engage in a new perception of their daily environment.' The device uses two LDRs (light depending resistor) mounted on a suction cup and analogue synthesizer, which converts the light input into sound waves. It ‘listens' to the light from a visual display, monitor or screen and plays it back through a basic synthesizer circuit amplified by a portable speaker. The portable L.S.D. can be attached to any video display, converting it into a synchronized, low-fi sound in real-time. Here are some examples of the L.S.D. in action:
