Photoreductive Pixel is a modular installation build upon photosensors and LEDs arranged in an array. The amount of light falling on the backside is recognized by a photosensor, interpreted by a microcontroller and displayed by a LED on the frontside. Every pixel has its own sensor and light emitting diode. They can be arranged within modules of nine pixels into arbitrary formations by plugging them together. This results in a pixelated layer within a room that is based dynamically on light and shadow created by interacting with the object.
