The scintillating grid illusion is very similar to the Hermann grid illusion and was devised in 1994 by E. Lingelbach. Like the Hermann illusion the image consists of a grid of black squares divided by lighter colored lines, however unlike the Hermann illusion this one has white circles already present at the intersections. This time when you stare at the image the white circles appear to have black dots appearing inside them.
Is this freaking realllllll Mega coooollll!!!!!!
