Have you ever wondered why your brain decides to see things a certain way? How your brain can look at an image and perceive it to be something that it is not?
Take for example: 
If you want to see the gears move, stare at the center dot and move your head closer to the screen. If you move your head closer to the screen and then away again, do you see the gears move? Cool huh?
Consider this image now:
It moves all by itself! Or does it?
Optical illusions, visual deceptions – it makes no difference what you call them, they are bizarre and in some cases beautiful.
