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.
