An implementation of Conway's Game of Life using Emacs' support for XBM images. Requires a graphical Emacs instance to run.
Install from Marmalade or MELPA
(Stable) via M-x package-install RET xbm-life
RET.
Alternatively download the xbm-life.el file, open it in Emacs and
execute M-x eval-buffer.
Run M-x xbm-life for the demo. You can run multiple (mostly)
independent demos along each other by either renaming an existing one
with M-x rename-buffer and running M-x xbm-life for an
additional one or by perusing C-u M-x xbm-life to give the one you
launch a different name. The timer is global however, therefore all
spawned demos run the same speed and get paused/unpaused at the same
time.
You can get an idea of the current details of the demo by taking a closer look at the modeline where key indicators (such as grid size, tile size, etc.) are displayed.
