This is a good one. I wonder how they done that. Keep the illusions coming.
They arn’t they are different shades of gray like GREY and GRAy

Wonderful! Can see it without the ruler
me too if i stare long enough
how can people think its A?

WHERE DID YOU FIND THE BRAIN PATTERN FOR MY LAST BOYFRIEND
hold up now! Which way does it go

hmm.. i have seen better versions of this illusion. the nose could be longer & below that it could be more distinctly mouth & chin, instead of equal bumps. neverthless, a good classic optical illusion

I would have to say 2, as to me it looks like an open box or crate, Good one
ive seen this on a cerial box there is no answer

you really don’t need to move your eyes to see it. It is so cool what your eyes will or won’t see
WJSMama; that’s weird) I found that if you move the page up and down with your cursor, you see loads of spokes!

Although one appears larger, I believe they are the same size. Good illusion.
cool illusion. if you’re not convinced they’re the same size, cover up the surrounding circles.

I used to have this as an avatar (so I love it) but it was too big and then the avi size was reduced. I love optical illusions
seen it too many times before, but it is still a good one.

I like that illusion. It took me a while to see that the lines on the square were actually straight!
it looked like it was mooving to me… but thats just because im crazy

This one I really like! Very interesting
I love this one! Where do you find these!!
I like the woman much better. Cool illusion
