Disappearing Dots

There are 12 black dots on this grid.
The crazy part is you cannot see them all at once.
It’s neurologically impossible.
Instead of seeing all 12, the dots seem to twinkle on and off.

Scientists invented the Scintillating Grid Illusion in 1997.
They say the grid tricks your brain into seeing a pattern that doesn’t exist.
The internet went bonkers when game developer Will Kerslake tweeted the Scintillating Grid in 2016.
Part of the reason the illusion works is because humans do not have the best peripheral vision.
When you focus in on one dot, the others seem to disappear.
