This is probably not a good test to do if you are feeling slightly the worse for wear after a fun evening. You wouldn’t want to be seeing extra spots in front of your eyes. And that’s exactly you might be seeing in this clever little test.
The test consists of a picture of white with black spots. But hidden within the picture is something rather special. Your mission is to try and find it as quickly as possible. If and when you do find it, please just write found it in the comments section, in order not to spoil it for the others who want to play along.
