# Conway's Game of Life in a Hestified way
# https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life
# https://ivanish.ca/hest-podcast
#
# To build:
# $ ./translate hest-life.mu
# I run it on my 2.5GHz Linux laptop like this:
# $ qemu-system-i386 -enable-kvm code.img
#
# If things seem too fast or too slow on your computer, adjust the loop bounds
# in the function `linger` at the bottom. Its value will depend on how you
# accelerate Qemu. Mu will eventually get a clock to obviate the need for this
# tuning.
#
# Keyboard shortcuts:
# space: pause/resume
# 0: restart time
# l: start looping from 0 to curren time
# L: stop looping
# +: zoom in
# -: zoom out
