#Visual Illusions in CSS3

As an experiment to push my ways of thinking about what is and isn't possible with CSS3 I decided to create a number of famous visual illusions using exclusively CSS.

These include:

• The Illusory Contoured Tilting Pyramid by Pietro Guardani & Luciano Gamberini from the University of Padova
• The Mutually Interfering Shapes Illusion by Maarten Wijntjes, Robert Volcic & Tomas Knapen from Utrecht University
• A variation of Lucy in the Sky by Arthur Shapiro & Justin Charles
• Grouping by Contrast by Erica Dixon, Arthur Shapiro & Kai Hamburger
• Breathing Square by M. Shiffrar and M. Pavel
