Fraser-Wilcox Illusion

Caption

The Fraser-Wilcox illusion arises from a simpler pattern than the one above. When viewers attend to this pattern while looking away from it, for instance looking elsewhere on the page or monitor, the pattern will appear to rotate slowly clockwise for some viewers. Flies are subject to a similar illusion of motion with this pattern.
