Is the picture below an optical illusion? It is made up on concentric squares of the same colour, yet the diagonals appear to be brighter. See this flash animation from MIT based on research by Edward H. Adelson which discusses the effect. He seems to think this is a true optical illusion. But I’m not so sure:
If a blur is conducted on the image then these diagonals become even more pronounced. Is this a visual phenomenon or are the diagonals really brighter?
Here’s a closer look at one diagonal from the original image, followed by a slice through a non-diagonal section. While enlarged they are both in the correct relative proportions. Do these help explain the phenomenon?

In the late forties, visual researcher Adelbert Ames Jr. designed a series of visual illusions to demonstrate how the mind forms hypotheses about reality and depth. In one such illusion, Ames tested aspects of depth perception in a specially designed, distorted room.

Remember that picture? You know, the one that you thought looked like something else and then you realised it was just a lamp? Well, maybe you were right the first time!
