Purple Nurple Illusion

The Purple Nurple Optical Illusion by Walter Anthony

Time for more fun with illusions. Created by Walter Anthony, this vivid optical illusion moves despite being a still life creation.

Illusions like these are part-psychology (interpretation, imagination and memory) and part-physiology (depth perception, focus, attention and eye movement). But looking too much into the neuroscience of illusions can take the fun out of the experience.

So, just marvel in the magic of how this static object swirls, contracts and expands. And visit Mr. Anthony's webpage for more fun.
