viewers (1) communicate bi-directionally, receiving live streaming video and communicating to a central server. The central webserver (2) in turn, is both re-broadcasting in one direction a live video feed from an on-site location to users, and in the
other direction, sending users clicks to the on-site location. A central control machine at the on-site location (3) is both
streaming video out, and turning users clicks into signals which control the installation using serial communication. Finally, a physical installation (4) includes the mechanical device and its motor control system, as well as a camera that documents its movements.
