WTF O_O

It's not an optical illusion.
It has a bit of javascript in it that causes the image to change when you rollover it with the mouse.

Nope
I thought that
Stared at the same area longer the next time
and as soon as I moved my eyes it was Black and white

Wow thats creepy.

Thats cool.

It took me 3 tries but its worked.

Oh thats cool!..

i had my mic on mute incased a scary face popped up and someone screamed lol..

My eyes!

Its not, its a black & white image but if you stare at the dot them move your mouse but don't move your eyes, it looks like its in colour until you move your eyes.

Nothing pops out and scares you does it?

Oh.
I was doing it wrong =|

Nope :spin2:

You can see it fades back to black and white after you've put the mouse over it lol

Try staring for longer at the dot, it stays in colour

Thats amazing! Impressed my mum aswell!
haha, I love it!

why is it so confusing? :puzzled: stare for 30 seconds at the dot dont move your eyes and put the mouse over the pic! it appears in colour when in face it black and white! :whistle:

made my eyes funny mind! :whistle:

i kept my eyes on the dot it stayed in colour for ages til i moved my eyes

WOW
Thats great

That's cool!

Same, I've experianced that wayyyy too many times to trust optical illusions. :sad:

its all to do with the colour of the image before you move your mouse over it. its nothing to do with the dot. the dot just gives you a point of refrence to look at. Its the colours that your eyes get use to and then when it suddenly changes yours eyes take a few seconds to adjust to the sudden change in colour giving the illusion that its actually in colour.

Its not that good..

wowwwww

WOW!

It doesn't, put your thumb so you can't see the dot, look again and move your mouse over, its not in colour at all and theres no fading

Oooooh, purdy.
