OPTICAL ILLUSIONS

If you stare at the following picture long

enough,you should see a giraffe…

SPOT THE GIRAFFE

This one has a couple different cool things. First, if you follow the pink dot moving, the dots will remain pink, but if you stare at the plus sign in the center, the rotating dot will turn green.That’s cool, but now try this... focus on the plus sign in the centre for a short period and all the pink dots will disappear and all you will see is the green dot going around! cool huh?

PINK DOTS

Stare at the black dot...

after awhile, the gray haze around it

will appear to shrink.

BLACK DOT

There aren’t any black dots in this image.
