This musical wall is a recent project designed by Montreal-based interactive media specialists Moment Factory to stimulate children’s imagination as they wait for their doctor’s appointment. The experience, which is located at the CHU Ste-Justine Hospital, is comprised of a projector and motion sensors.

The experience begins when hospital visitors touch the wall. By moving their hands and fingers around, they produce vibrant lines and shapes that trace their movement and produce musical notes. Check out the video below to see the wall in action.
