Every time you view a movie, your eyes participate in some special effects "magic". What appears to be movement on the screen is really a series of static frames. These frames are played at a faster rate than the eye can register the brief pauses between each frame, thus fooling the eye into seeing "motion". To understand how this is possible, Silicon Graphics Computer Systems has created the frameplayer below. Have fun slowing down the motion, reversing the action, playing the movie frame by frame, and then at normal speed to see how your own eyes can create special effects.
