@daltonjamesyt: I Made a Scintillating Grid Optical Illusion Out of SAND! (Oddly Satisfying) If you stare at the grid and let your eyes wander across the white dots at the intersections, you might notice dark spots appearing and disappearing in your peripheral vision. It's a classic trick of the eye, made even more satisfying by the smooth, precise application of the colored sand! What is a Scintillating Grid? The scintillating grid is a famous optical illusion where illusory dark dots seem to flash or "scintillate" at the intersections of a grid when you move your eyes around the image. However, as soon as you focus your eyes directly on a specific white intersection, the dark dot instantly vanishes!
