Illusions

 

the horizontal lines are perfectly horizonal



the grey are the same color



The outer is a perfect rectangle



I'll let you work that one out :)




perfectly the same but one square empty!





if you're not looking at the white circles
they become black
 

if you stare at the white, the black will increase




am I reading or are you?
