What's cool about this for me is that, even though I'm somewhat red-green color blind, everything this illusion purports to do, happened! I feel 'normal'! Can I learn the secret hand shake now? Huh? Please?

For me the pink dots turned into tiny breasts; clearly I have to stay away from the boobs on the sidebar arguement!

I like this one (which may have been up on here before?) - especially for it's relevance to B&W images and the adjacent shades/tones therein:

Squares A and B are exactly the same shade of grey

Yup, and it's one of skepticism.

The brain can only do one thing at a time, just like any computer.

By concentrating on one thing, the secondary image becomes background noise, so to speak. Eventually the brain discards the background image so it disappears.

When we first start talking to someone in a crowded place, the background noise makes conversation hard, eventually the brain drops off the background noise and a conversation in a loud place, becomes comparatively easy.

The rotating image is always disappearing and reappearing so the brain still holds that image as the moving image is there at every refresh, but in a different position.

That is what I think happens.

The green dot is there because of the brains automatic color balance response. It's trying to even out the magenta color by making a negative bias on it and when the pink dot disappears the negative image shows up. As you stare long enough the brain sucessfully cancels the magenta colors and you only see the negative color showing when the magenta dot disappears.

I found this one today, via kottke.org...

They rarely are ....

Huhhh?

So that is what an acid flashback looks like.

Yes. Perception is everything. There is no reality outside that which our brains create. (David, put down the joint and mull that one over for a while )

So what the hell are we doing driving around happily chatting away on our cell phones.

Well my eyes hurt now so I'll have to get off the computer and think about all this and then I'll have a headache.

Our vision is selective. And our brain is too. Few months ago on PBS TV channel in my country was documentary film about vision. In one sequence about 30 people was asked to watch big TV screen. On screen were 2 groups of basketball players. Each group had 3 member. One group was dressed in yellow outfit and other was dressed in black. People who wached was asked to count how much will member of yellow dressed group pass the ball to each other. Yellow and black were mixed, not separated. After some time, leader of experiment asked audince are they noticed anything strange. Only two persons of 30 confirmaed there was something strange. Then leaer of experiment rewoud tape and now adked people to look what happens generally on TV screen, not to concentrate on anything specific. And he played same scene again. At one moment, man dressed in monkey costume appears, stayed in middle of TV screen, and even beated his chests, like we see gorillas do. And that lasted 5 seconds, maybe more. Only 2 person of 30 people noticed it in first place, without warning. I think I still have tape of that exeriment somewhere, narrator of documentary told during the film to tape it and to check for ourselves. I don't think there was cheating. And after rewounding and watching same film again I noticed that monkey dressed man atleast 5 or 6 times during the film. And only after narrator inform at the end of the movie to wach it again. Som our vision is selective, ans we have much less capable brains than we like to think...

Pink dots stayed but had a constant and large green circle behind the pink the dots. I guess this proves that women can multitask and that I spend too much time on apug!

I just love giving out a Greenland zip code when some shop asks me for my zip code for statistic purposes...then look so funny when it doesn't work with their system
