Heya, I'm new to the site - what's the purpose of the OR in T=t|0? Is t sometimes undefined?
u/rep_movsd

t is time, but its in floating point, t|0 makes it an integer

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
