Conway's Game of Life using ffmpeg
(trac.ffmpeg.org)
ffplay -f lavfi -i life=s=400x300:mold=10:r=30:ratio=0.1:death_color=#C83232:life_color=#00ff00,scale=1200:800:flags=32
nice, TIL ffmpeg knows how to triforce
ffplay -fs -f lavfi -i cellauto=rule=90:p="$(printf %480s%480s 1)":s=960x540:start_full=0:r=120(docs, wikipedia on rule 90)
