A mind-bending optical illusion has gone viral on Twitter this week. Called the Perpetual Diamond, it features a purple diamond on a grey background. The puzzling optical illusion will make your brain think that the diamond is moving on the screen, even though it stays completely still. The illusion is achieved with the help of a series of flashing lights behind the image which trick the brain into thinking the shape is moving in different directions.
The optical illusion was created by researchers Oliver Flynn and Arthur Shapiro from the American University in Washington DC, reports BBC.
The optical illusion was shared online by Arthur Shapiro, who wrote: "The diamond remains fixed in one place but appears to move up, down, left, or, right. See how far away you can be from your screen before the effect goes away."

The spectacular illusion is produced because of the diamond's flashing background in combination with its thin borders, the researchers explained. The illusion can be potentially used as a tool for tests of spatial contrast, temporal contrast, contrast gain, and color contrast.
