OPTICAL ILLUSIONS

A friend of mine sent me these and I thought they were so cool that I decided to post them. Just follow the links and the explanations are given.

Count the black dots

Say the color, not the word (really tough)

How many legs does an elephant have? ( I stared at this for many minutes)

The disappearing haze

Straight lines?

Moving circles (This is the coolest I have ever seen!!!)

Try to build THIS!!!

Who do you see?

They are not really moving.

Are the purple lines straight or bent?

Which circle in the middle is bigger?

What else besides a man's face?

Is this possible?
