Is it...?

Optical Illusions!

Stare to the right of the snakes! They appear to be moving!
Stare at the little square in the center. Is it moving?
Keep staring at the black dot... 
Stare at the black dot.
After a while, the gray haze around it seems to fade.


Stare at the black lightbulb for at least 30 seconds.
Then look at a white part of the screen or a white sheet of paper.
You should see a glowing lightbulb!


Stare at the gray dot.
Stare at the gray dot in the center...

Now move your head forward and backward.
As your head moves closer to your monitor
and then back away from your monitor, the circles
will appear to be spinning. 



The Red, White, and Blue...
 
The Red, White, and Blue...
 Stare at the center of the weird flag for about 1 minute.
Don't move your eyes. Then look at an empty white sheet
of paper, and you'll see the red, white, and blue flag.
