Optical Illusions

If you look at the above images from your seat in front of the computer,
Mr.Angry is on the left, and Mrs.Calm is on the right.
 
Get up from your seat, and move back a couple of feet, and PRESTO!!
they switch places!!

Keep Your Eyes On The Dots
==================

You see a circle of violet dots.
Each of them disappears in order, like moving in a circle.

Concentrate your sight at the cross,
then you can see how the violet dots disappear.
If you do it all right,
you can see that the green dot is moving.

If you keep looking all violet dots will disappear
and only green dot will keep moving!
