Early pedestrian traffic lights used green and red signals to convey messages: a green light meant pedestrians could cross, while a red light indicated they could not. Today’s little green man pedestrian signal consists of seven different patterns that use the persistence of vision effect to create the animation of a little green man walking or running. When the little green man walks slowly, it means you still have plenty of time; when he starts running, it’s a reminder to hurry across; and when he turns into a little red man standing still, it means pedestrians must not cross.
