Yes, I hadn't noticed it, but John Horton Conway died a few days ago. To load the "game of life" mappings once Vim is up, :runtime macros/life/life.vim
then (in Normal mode) either g (go); or I (uppercase i for initialize) followed by either C (compute one step) or R (run). After I you can edit the left field to change the seed. Note: AFAICT, once you have started computing all successive generations recursively by g or R, there's no way to stop the automaton short of killing Vim. Best regards, Tony.
