They experimented endlessly with how an animated character should move, finding a new kind of stylized realism that carried conviction without mirroring the real world. The animation expert Ernest Rister writes: "I wonder if they knew that finding a technique for investing a drawing with a sense of weight and volume would someday be used to create killer bugs or a giant snake in the Amazon.
