The Ebbinghaus Illusion

A lot of these new illusions are still just sort of riffs on the classics. They use other things surrounding something to trick your brain. One that won a couple of years ago in 2014 was a new version of the Ebbinghaus illusion where it's actually a video that you have to play. The orange dots are the same size but they look completely different sizes. And I think this is one of the ones that, and they have this contest every year, I think for like, I don't know, it's been going on for at least 10 or 12 years with new illusions.
