1-   Is this possible!?!

2-

3-

4-

5-   Are the horizontal lines parallel or do they slope?

6-

7-  Are the purple lines straight or bent

8-  Focus on the dot in the centre and move your head backwards and forwards. Weird hey …

9-  Do you see gray areas in between the squares? Now where did they come from  ?

10-    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

11-  You should see a man's face and also a word...
Hint: Try tilting your head to the right, the world begins with 'L'
