The trick is when you mouse over it, it loads another image. Not that big a deal, until you move your eyes and realize that "true color" image you thought was there is not black and white.

This is not an animated image. It's a JPEG so that's completely impossible. Focus on each spinning circle and you'll see for yourself. So, either the computer is sensing your focus and freezing each circle, or there's yet another glitch in your visual system being taken advantage of!

Close up, one looks angry. Far away, the other looks angry.

If you needed any more evidence that our brains are essentially computers that store data "holographically" (not literally a holograph like on star trek!), here it is. Look at the crosshair and not only will the surrounding magenta dots vanish, they will vanish SEQUENCIALLY as the "green circle" (actually just empty grey space where a magenta dot used to be) crosses over it, then they fade back in, then out again sequencially, all rythmically so you can time exactly how long it takes for your brain to "figure it out".

Do a cut and paste of that image and you'll see for yourself that A and B are the same color.

My problem with this one is it has never worked for me. I always see it as concave. It might simply be because I've seen this since I was like 3 so my brain knows what it's seeing at this point.
So basically, with illusions like these tricking us so completely, it's small wonder I don't really bother trusting the average gaming site's review of "slight motion blur" without more evidence than mere testimony.

"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
