Nice! beat me to it, although i'm doing something slightly different... progressing at a rate of -4 chars per day :P

This grid takes about 850 generations to stabilize between 2 states! "Theoretically, Conway's Life has the power of a universal Turing machine: anything that can be computed algorithmically can be computed within Life."

Clicking tags I realized the sheer number of cool #gameoflife dweets of times yore. 😲
u/tomxor

Yup, some of the oldest ones from 2017 are quite impressive and completely ucompressed, although that tag is a bit polluted with serpinski triangles later on.

The formula generates pseudo random numbers for r=4, but the distribution is not uniform.
