Contemporary artists sometimes use the canvas as if they were magicians. With little tricks they show us reality… as it never is! Bridget Riley is an artist-illusionist.

Bridget Riley has introduced movement into her work through a very simple optical illusion. Its title, Static II, is deceiving. The canvas is anything but static; it seems alive!
