Driving people dotty: Crazy optical illusion goes viral (POLL)
The image, called ‘Ninio’s Extinction Illusion’, contains 12 black dots dispersed in a pattern such that the human brain finds it difficult to ‘spot’ them all at once.
While the dots are evenly located throughout the image, the way light receptors in people’s eyes function means they can only see three or four of them at a time.
The extinction grid is a variation on a classic optical illusion, the Hermann Grid, which dates back to the 19th century.
On Sunday, the bizarre Ninio illusion was shared by a user on Twitter, who found it on Facebook, and it has since been retweeted an incredible 24,000 times.
There are twelve black dots at the intersections in this image. Your brain won’t let you see them all at once. pic.twitter.com/ig6P980LOT— Will Kerslake (@wkerslake) September 11, 2016
Some Tweeters simply couldn’t handle the ‘challenge’.
@wkerslake is this the human equivalent of a laser pointer for a cat? I keep chasing it... but I can't catch it....— Kurt Seifried (@kurtseifried) September 12, 2016
But we want to know...
