This game works in a similar way as the earliest forms of analog animation. As Rebekah Modrak states in her book and on her website, Reframing Photography, thaumatropes (an early form of animation) “ depend on the persistence of vision to blend individual images, thereby creating the illusion of continuous motion.” In this case, single images randomly appear in our frame of view, one-after-another, thus making it appear that the being is toddling.
