A mind-blowing optical illusion has taken the internet by storm – and it has been driving everyone crazy.
At first glance the illusion appears fairly simple, just two squares on a grey background.
The image is split into two sections – a smaller square in the centre and a larger square bordering it – both of which feature the same woven pattern.
But if you look closely, you’ll notice something very odd about the square in the centre.
The baffling picture was originally shared by a Reddit user, who captioned it: “This is not a gif.”
Since then, users have been desperately trying to work out how the illusion works – can you?
Since it started circulating on the site, it has received 25,000 upvotes and over 450 comments from confused viewers.
One person said: “It’s like a portal into another dimension. Very intense.”
Another said: “Depending on which eye I use, the inside or the outside wiggles. Wtf?”
A third added: “Keep your eye in the same spot and just scroll down slowly, and it STILL MOVES.”
