Art as Visual Research: Kinetic Illusions in Op Art [Preview]

RILEY REVISITED
In a work reminiscent of Riley's, vision scientist Nick Wade of the University of Dundee in Scotland created an example that features both streaming and shimmering motion.

The hidden face is a portrait of Wade's wife, Christine, and the title Chrystine is a reference to the chrysanthemum shape.
