The motion of a living thing depicted by just the motion of specific points on the body. Originally generated by filming actors in darkened rooms, wearing dark clothes with lights attached to the joints. By adjusting the contrast of these films only the motion of the lights was visible.

The point-light display shows the motion of the actor with the majority of other person information subtracted from the display.
