See this image appear to shimmer as you look at it? If that's not enough follow the ridge around the circle and watch it change into a groove...

OK, a very straight forward test for you. Simply read out loud the following list of colours, remembering to read the text only...

Each of the 3 curves shown above are sections of the circle.
Which would form the largest circle though?

Checker Shadow Illusion

This fantastic illusion was created by Edward Adelson. (http://www-bcs.mit.edu/people/adelson/adelson.html)
Incredibly, both A and B are the same shade of grey. These type of optical illusions usually just use simple contrast to fool the brain, but this illusion employs two effects. First of all, it plays tricks on the mind thanks to the dark shadow contrast around B - but the effect is reinforced by the bright white background contrast near A.
With some 'training', it is possible to see both A and B as the same shade, but otherwise you might want to import the picture into a paint package to prove it to yourself.
