Particularly liked this statement, from Joseph and Barbera Anderson:
                    "There is no motion on the screen,
                     just a succession of still images. If
                     there were persistence of these
                     images in the eye of the viewer,
                     figures on the screen would pile up,
                     one on top of the other, resulting in a
                     kind of chronophotographic display."
-- in other words "trails".
