optical ILLUSIONS

Mga kaberks, I wanted to share with you some of these images sent to me by my friend Richard from Chicago. This is the Optical Illusions:

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'

I really find this interesting. Try n'yo lang.
