I've always known that the human brain is *way* too eager to find patterns in random noise.
But there's something about watching my brain automatically attempting to construct meaning out of random program output – output that I *know* is random because I wrote the program! – that really drives that point home.
@codesections Sometimes, though, the pattern *really is* there. See https://upload.wikimedia.org/wikipedia/commons/a/a3/Lcg_3d.gif for an example.
@ashwinvis the pseudo random number generator (PRNG) used for the GIF is described here : https://en.wikipedia.org/wiki/Linear_congruential_generator
And one possible analysis on a PRNG is the « spectral test » that you can apply on two or more dimensions, see https://en.wikipedia.org/wiki/Spectral_test
