A playful drawing machine that permanently archives human activity

A playful drawing tool that visualises human occupation within a space during the course of a day. As the sensor is triggered, the pen drops, causing lines to form across the paper disc. The arm of the device moves outward every hour, and the length and density of the lines begin to reveal the duration and frequency of each visit. Each disc produced becomes a beautiful visual artefact, a physical recording of the history of both how and when the space was used, which in turn can reveal a potentially unseen character of the room.
