Probably one of the coolest mind tricks and optical illusions I have ever seen!
If you move away from the center you can see the circle start to move.
Focus on the middlle and you shall see the circles start to move.
It would appear the eggs are moving but they really arn't!
Here is another counting illusion. How many faces can you find.
There is only 3 Colors in this picture.
Stare at this illusion and be prepared to see weird things.
These lines are actually parallel even though they appear to curve.
The square in the middle appears to be curved but its perfectly straight.
Here's an entertaining show put on by 2 guys and a pommel horse.
