d/24820

u/taupelink

Prompt: "Make something that will look completely different in a year." Date.now() is used as a seed for a pseudorandom number generator. The pseudorandom number is modded out by various prime numbers to determine components of the collection of blocks.
u/taupelink

So, the sequence is different each time you load the dweet. #genuary #genuary2022
