Optical illusions are the ways our brain gets tricked. In optical, we perceive a particular image in a different way than it is actually present. Our eyes are capable of interpreting the reflected light into sight. Our eyes help us to determine distance, color and location of the different objects that are around us and it does that within seconds. Optical illusions take this weakness of the visual process in offering the result that is different from the actual object. The brain gets confused when motion is associated in the visual process. When we look at the animated image of a wheel that is rotating, the brain tries to represent that movement as rotation as the brain has seen the wheel earlier. In reality the .gif image is stationary and it gives the animation effect by moving back and forth. This is how the films and movies work in reality. The TV shows which are watched by so many people are also made of dozens of single pictures that are played rapidly in succession. The brain sees a person on one side of the screen, and when it becomes a little closer to the other side of the screen, the brain assumes that it is walking like any other person.
Animated Optical illusions have their immense uses in the graphics and animated shows.
Look at the nine different illusions and figure out how many of them are moving.
Move close and away from the screen and every time you will see the spiral moving in the opposite direction.
