Unless you've been living under a rock for the past few years you will remember 'the dress'.
Was it black and blue or gold and white?
'The dress' literally broke the internet because nobody could make their minds up.
Well, now there's a new optical illusion going around ...
The illusion - which was posted on Twitter - asks viewers to share what number they see in the image.
But despite more than 7000 responses, the answers vary wildly.
Some of the answers that rolled in included 528, 45283, 15283, 3452839 and 845283.
The correct answer seems to be 3452839, which is more apparent when you increase the contrast on the image.
The University of Queensland's special Queensland Brain Institute branch had a simple explanation for vastly different responses when it came to optical illusions, saying: "Sometimes, our brain gets confused by what the eyes are trying to tell it," the institute wrote in a blog post.
"Our eyes and brain speak to each other in a very simple language, like a child who doesn't know many words. Most of the time that's not a problem and our brain is able to understand what the eyes tell it ... Sometimes, however, the brain guesses wrong."
