I had a dream when I was napping where arranging the multiplication table in a certain way modulo a particular number, and shading the results from black to white, would result in a photorealistic photograph of a bear
it was named "rogin's bear" after the presumed discoverer
@SuricrasiaOnline I want to start using this term for any unexpected and peculiar emergent phenomenon. "Black swan" was originally a financial term but is used in IT for an outage that cannot be anticipated, and thus is difficult to harden against. "Rogin's bear" could be, e.g., when code is compiled and then opened in a binary editor, displaying a Fibonacci progression when a specific language and specific software versions are used.
