I was sent this from a friend and I thought it was very interesting.
So Im sharing it with you all. The rest is from my friend including the text?
Copy and paste for the win 
Are the purple lines straight or bent?
Do you see gray areas in between the squares?

You should see a man's face and also a word...
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 look 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
Thanks for the Memories MXO!
