      It’s a gif of a couple perlin noise-looking squares, one overlaps the other slowly, pausing to reveal a brief momentary perfect alignment which breaks the otherwise undiscernable patters and displays a prominent red A in center of a white square

      The patterns are identical, except for where the A is. So, when you overlay the black pattern perfectly, it mostly hides the red pattern.

      And then where the A is, the red pattern is colored in such a way that it fills in the gaps of the black pattern, leading to a solidly colored area there.
