This stationary image appears to wave without effort. The elemental illusion is our revised version of the peripheral drift illusion, in which the direction of illusory motion is black-to-dark-gray and white-to-light-gray (Kitaoka and Ashida, 2003). In this image, blue and yellow correspond to dark gray and light gray, respectively.
