Last year we covered the 'coffer' illusion, a visual riddling that was blowing/bending/frying/breaking the internet's collective mind. And like all the best illusions, it seems this one keeps on giving, as new scientific research has revealed that your perception of it could be influenced by one unexpected factor.
For the uninitiated, the coffer illusion depicts what appears to be a series of rectangles – but actually contains 16 circles. They're initially hard to spot, but once you've managed it, they can't be unseen (spoiler alert: they're in the gaps between the rectangles). How quickly you find the circles, though, could depend on where in the world you grew up.
