These autonomous lamps by Dutch designer Bob de Graaf seek out human companions then follow them around, and go in search of the darkest spots in the house ( + movie).
De Graaf‘s interactive lights, collectively called Species of Illumination, were given the ability to act like creatures via a series of sensors, motors and stretchable cables that allow them to freely determine their actions.
The series consists of two lights. Wallace uses sensors to go in search of the darkest spot in a room and bring light to it. Once it has done that, the lamp works out where the next darkest point is and moves on to repeat the process.
