Optical Illusions!

 Look at the image below.
Do you see rectangles or diamonds?

Take a look at this one. 
There are NO black dots anywhere in the image.
Your brain gets confused and your eyes create
the black dots inside the white empty spaces!

What's going on with this painting?

None of the circles below are actually turning. 

The ones you look directly at are still,

but the others appear to move.

It's all in your head!

Amaze your friends with these optical illusions!
