April 2014 ImageThese nested squares constitute a variation on the Ouchi illusion, which is produced by orthogonally arranged lines of alternating light and dark regions.

The illusion is the apparent motion of the center and surrounding squares relative to each other. Eye motion is required for the illusion to appear, and saccades – rapid unconscious eye movements – are generally sufficient. The illusion is most pronounced in peripheral vision, which is more sensitive to movement than central, fovial vision. Rodney Schreiner, researcher and educator in the department of Chemistry, focuses on the relationship between perception and underlying physical stimuli.
