Apparently there are twelve dots in this optical illusion, but it's near impossible to spot them all at the same time. How many can you spot?
An optical illusion by Jacques Ninio created in 2000 has been doing the rounds on social media recently and people have been struggling to work it out!

It feels as though as soon as you spot a few of the visible dots, the others disappear!
