This mind-bending optical illusion has sent people spinning. But can you figure out why?

The baffling brain teaser showing a series of distorted shapes has Brits going around in circles while trying to decipher it.

This trippy mind trick appears to consist of a long spiral of small black and white squares.

It seems like the static image is spinning before you look at it.

It has just tricked your brain into believing the formation is a spiral, despite it being only four concentric circles.

This is when a series of rings have a common centre - and in this case, can trick illusion lovers into seeing a rotating spiral.

Each of the tiny squares that make up the diagram is positioned at an angle that distorts the view.

It's difficult to grasp even when everything is explained.

Only four concentric static circles make up what appears to be a spiral moving in motion.
