An optical illusion is blowing up on Reddit, with 2,000 people commenting to respond to the question "what number do you see?"
What may look like a swirling set of circular lines actually includes a set of numbers, and they only become clear one at a time – you have to spend some time staring at this one. Shared by rastroboy, this may not be one of the classic optical illusions out there, but certainly an entertaining one. It is super confusing how the numbers don't show themselves straight away.
