(very) MILD EPILEPSY WARNING A little shader script I made here: shadertoy.com/view/sctSDH Basically, each pixel has an X and Y coordinate. On a computer, this coordinate is stored by 2 binary numbers, for example: 00010, 10111. We apply XOR to them. That way we get: 10101 Then, we convert that number (10101) into decimal. In this case, that gives us 21. We check if that number is a Twin Prime. If it is, we color it pink. If its not, we color it black. We do this for every single pixel. That generates the pattern. 21 in this case isn't a prime (7x3=21) so we color that pixel at position 00010, 10111 black. We also apply a little animation on the start to make it look a bit alive.
