This is weird...
 

If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.

If you stare at the the black + in the center, the moving dot turns to green.

Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating.

It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. This should be proof enough, we don't always see what we think we see.

I've got one of these too....
Stare at the picture for about 40 seconds, then look at something bright, like a lamp and you see jesus!

Re: This is weird...
 

I have one of these illusion things too, but I don't know how to attach them to my post :(

Re: This is weird...
 

Just post a reply and below that, in additional options, there is an option to "manage attachments". Choose that then upload the file.

Re: This is weird...
 

OK, thanks for that!

In this picture you will see two squares with a dot on them. Believe it or not they are the same colour.

You can open the image in Paintbrush, and cut and paste the squares next to each other to see.

But thanks for posting it anyway... it's one of my favourite optical illusions. :)

Re: This is weird...
 

"Physiological illusions, such as the afterimages following bright lights or adapting stimuli of excessively longer alternating patterns (contingent perceptual aftereffect, CAE), are the effects on the eyes or brain of excessive stimulation of a specific type - brightness, tilt, colour, movement, and so on. The theory is that stimuli have individual dedicated neural paths in the visual outer wall of an organism for the early stages of visual processing; repetitive stimulation of only a few channels misleads the visual system."

http://en.wikipedia.org/wiki/Optical_illusion

Basically, when you see pink all the time, the "pink receptors" either get tired or discounted and this generates a "negative image" effect where the opposite colour is seen, even though it isn't there.
