Optical Illusions

This is interesting. Ok. Although most of the others are quite common, but I think the 7th illusion is the most amazing. This shows that how power our eyes and brain are!

Click photo to enlarge and try it.

Is this possible?

Are the purple lines straight or bent?


Do you see grey area in between the squares?
Now where did they come from?


You should see a man's face ans also a word...
Hint: Try tilting your head to the right, the word 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 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
