The page also has explanations on why/how they occur (in icky PDF format). The page is on a .jp uni server so they SHOULD be able to handle the herd of rhinos that is ./."

How many of you swore that each checkerbox was different and got thoroughly pissed off when you checked the hex value with the dropper and they were the same?
How many of you physically cut and moved one box next to its partner and back again over and over, screaming in mental anguish as one moment they're obviously the same and the next they're two different colors?
Count me in. This illusion pisses me off.

Basically, colors always effect other colors. For example, if a gray square is surrounded by black squares, the gray square will seem much brighter than it would sitting next to other tones of gray.
If you surround the gray square with white squares, the gray square will seem much darker.
I guess you could call it the color theory of relativity.
This works with colors, not just with shades of gray. Surround a medium gray square by orange squares, and the gray square will take on a cool blueish hue (blue is complementary/opposite of orange), even if its rgb is 128,128,128.
In this optical illusion, the shadow cast from the cylinder onto the 'A' squares is affecting the appearance of the 'B' square. Its only the shadow thats causing the illusion.

What's interesting is that I blocked out the rest of the picture by covering it with other windows, leaving just parts of those two squares visible...and they STILL look like different shades.

Make sure you cover up the letters, too, or the contrast (one letter is light, the other dark) will trick your brain just like the surrounding squares. I was able to see through the illusion by covering up everything but the corners of both squares.

Some of the pictures on this website can cause dizziness or might possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

I didn't realize this was the cause of seizure fears. I happen to be completely blind in one eye, does this mean I don't need to worry about getting seizures from this sort of thing? If so, that's an interesting bit of news I never heard of... perhaps even the first (only?) perk of being half blind.

Wouldn't it also mean that you can't see the "illusion" at all? I'd be interested to know if the images still appear to wobble and roll and such when you look at them.
You could always test that out by closing one of your eyes ;)

The trouble was, the wallpaper was vertical blue and white stripes, each about 1 inch (2,5 cm) wide, covering both walls.
Sitting at the computer, seeing the striped wallpaper in your peripheral vision, you would get the unnerving feeling the monitor was attacking you, slowly approaching you, menacingly. (It didn't help that the monitor was on an elevated platform, so you actually had to look up at it.)
After a few years, they covered the wallpaper with wood paneling.
