The description of Sniffy's movements being created by flipping through the pages of the book suggests a stroboscopic illusion, which tricks the brain into perceiving motion where there is none. Looming refers to the way objects appear to grow larger as they approach us, optical flow refers to the way visual patterns change as we move through the environment, and motion parallax refers to the way objects appear to move at different speeds depending on how far away they are from us. None of these concepts fully explain the perception of Sniffy's movements in the "flip" book.
