Tvor, the intelligent lighting creature, is endowed with artificial intelligence that steers it towards the darkest place in the room. It seeks out darkness relentlessly, but its illuminating presence transfers the darkness to another place. Tvor is thus doomed to endless travel.

How Tvor works: it first starts turning on the spot, monitoring the intensity of light in all directions. Once it has identified the direction where the least light is observed, it dims down its own light and moves in that direction. It keeps moving until it detects an obstruction, usually a wall or a spectator. Tvor stops and lights up. It stays still for a while before starting to rotate again. The speed of this cycle can be regulated by a dial on Tvor’s body.

What’s inside: the main building block of Tvor is Arduino, an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other devices.
