Whats wrong with yr brain or yr eyes ?

Please enjoy the pictures that Sandy Leong brought to you. =)

Please look at those white lines , you will spotted grey dots , but when the minute you want to look more closer , the grey dot is gone !

In the image above, the shape can be perceived as either an inside or an outside corner.

If you look closer to the 2 orange dots , you will find that 2 orange dots , are the same size !

This optical illusion makes the parallel straight horizontal lines appear to be bent. To construct the illusion, alternating light and dark “bricks” are laid in staggered rows. It is essential for the illusion that each “brick” is surrounded by a layer of “mortar” (the grey in the image). This should ideally be of a color in between the dark and light color of the “bricks”.
