The internet is a mindfield when it comes to the optical illusions, between deciding whether a dress is gold or black it is never ending!
The latest craze to hit the internet is from game developer Will Kerslake, who has posted on Twitter something that will bamboozle your brains and will make you question your existance!!
The photo he shared shows a picture of a geometrical grey pattern on a white background ... so sounds pretty straight forward right? Until you realise that there are 12 black dots blinking in and out of existence at intersection points on the pattern.
The crazy thing is the black dots usually appear where your vision is focused and then the dots that surround it seem to disappear!
French scientist Jacques Ninio said that the illusion has to do with humans having unreliable peripheral vision
"When the white disks in a scintillating grid are reduced in size, and outlined in black, they tend to disappear. One sees only a few of them at a time, in clusters which move erratically on the page."
"Where they are not seen, the grey alleys seem to be continuous, generating grey crossings that are not actually present."
"Some black sparkling can be seen at those crossings where no disk is seen. The illusion also works in reverse contrast."
Woah mind is actually blown!
