Illusion

Is This Possible??

Are the purple lines straight or bent?

Do you see gray areas in between the squares?

Now where did they come from?

You should see a man's face and also a word...

Hint: Try tilting your head to the right, the world begins with 'L'

If you take a look at the following picture , let me tell you .... it is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or loo k at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it.... Weird

Is the book looking towards you OR away from you?
