Just move your head away and towards your screen and see how blue color expands and shrinks

What do you see in the illusion below? A horse only? or a frog only? Mostly people see horse but if you see it with concentration, you can also see a frog

So what do your see? The horizontal grey bar is made of two colors? Check again by covering the background and just seeing the grey bar.

The horizontal grey bar is of the same color throughout, you see the difference because of the difference in background. Amazing??

Do you see all these red-orange lines parallel/perpendicular to each other? If not see closely, all these lines are perfectly parallel/prependicular ( horizontal and vertical) but due to the background, they dont look so.

In 1939, psychologist William Orbison described the Orbison illusion. The inner square appears to be distorted due to the radiating lines. But actually its a perfect square.

In this illusion, one of the blue lines appear to be shorter than the other one. The left side one seems bigger but actually they both are of exactly the same length.

Check out those both black dots, do they look equal? Many people will feel that the dot on the right side is bigger but actually they both are of same size

So can you read what is written between these lines? If not just move your head away from the screen.
