Projection. Depth camera (Kinect) films the passersby. When two entities approach one another, interaction happens. Projected colored spots represent real people, while there are additional spots moving randomly in space. When someone enters the workspace a spot appears on the screen, and symbolizes one place. While roaming, when the spot comes across another spot, a tone is generated and a white line is drawn between them. The more such connections, the richer the work becomes.
