THIS tricky optical illusion is enough to make you dizzy.
The purple-yellow image appears three-dimensional and moving, but is actually stationary and flat.

It is an example of illusory motion, also known as a motion illusion, in which a stationary image appears to be moving.
They work by tricking the brain into seeing movement using contrasting colors, object shapes, and positions.
Because our brain reads the change in light as movement, the lines appear to be moving.
In reality, they are completely static. A similar trick is used to create the illusion of depth.
Interestingly, the trick relies on the viewer scanning the image with their eyes for the full effect.
If you keep your eye in the center of the image, the illusory movement slows down or even stops altogether.
Optical illusions are often just for fun, but they also have real value to scientists.
Brain puzzles help researchers shed light on the inner workings of the mind and how it reacts to the environment.
Dr Gustav Kuhn, a psychologist and expert in human perception at Goldsmiths University in London, told The Sun earlier this month that illusions are important to our understanding of the brain.
“We tend to take perception for granted and rarely think about the hard work that underpins everyday tasks, like seeing a cup of coffee in front of us,” he said.
“Visual illusions highlight misperceptions and provide important information about the hidden neural processes that allow us to see the world around us.”
It follows the release of a spooky illusion earlier this month that made the viewer feel like they were falling into a black hole.
