Modelling #bacteria #algae #coronavirus #growth with John Conway's #GameOfLife - special thanks to u/rodrigo.siqueira for the code slashing support!

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

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."
u/DaSpider

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.

Primordial soup #gameoflife (with changed rules to fit 107 bytes). Homage to John Conway (1937-2020), the creator of Game of Life and cellular automata, seed of ideas for Artificial Life, emergence, self-organization and complexity.

u/tomxor

Farewell John Conway, not his favorite discovery, none the less responsible for generations of programmers enjoyment.
