Nicked off NJCF...........

 

If you continue to focus on the cross in the center of the image you will notice that the circle of violet circles will soon DISSAPPEAR completely . . . and you will see only the green spot (which is actually nothing).

 

You MUST focus on the cross in the middle...

 

 

freaky!!

 

Anyone got anymore????????

Look at the cross, not around the cross but at the cross.... You under! :D

 

 

Thats ace rich!

its not an optical illusion - it just looks like one! :rofl:

That's ace Rich!

 

And if you ignore the cross and follow the green dot as it goes around it too disappears!

 

Freeky!

 

:D

 

Dan

And ur under !!

There's always this kind of thing....

 

 

 

 

1) Relax and concentrate on the 4 dots in the middle of the picture for abt. 30-40 secs.

 

2) Then, take a look at a wall near you (resp. any smooth, single coloured surface)

 

3) You will see a circle of light developing

 

4) Start blinking your eyes a couple of times and you will see a figure emerging…

 

5) What do you see? Moreover, who do you see?

5) What do you see? Moreover, who do you see?

 

A bloke with a beard picking his nose?! :rofl: :rofl: :slap:

 

5) What do you see? Moreover, who do you see?

 

Same as neil LOL.........

 

I think chunk's original is something to do with the fact that the brain perceives the magenta circles as the kind of "burn-in" effect you get when you stare at a bright light source and then look away, so it simply processes them out after a short while. I think the green dot is the result of it processing out the magenta that simply isn't there. In slightly more detail, and I fully admit this is my own hokey explanation and somebody on here is bound to know better:

 

Light grey is basically a slightly darker version of white, in that it's composed of equal amounts of red green and blue light (on a standard monitor). To process out the magenta your brain applies a correction to the red and blue components to make the splodges look the same as the surrounding grey background. However, it does not correct the green component... hence you end up seeing a green dot where there is none, or something like that anyway. Any advances on this from anybody else?

I've got a headache coming on...

This one might give you a headache.

The picture is not actually moving at all...

Eurgh! That's almost enough to give you motion sickness!! :))
