# Generate an astonishingly accurate, animated map of Utah with
# thousands of wildfire pins scattered around it by throwing dozens of
# random lat/lng pairs at the google static maps API.

# NOTE: This script requires ImageMagick. Good luck with that.

# Linear Congruential Generator using bc

# Note the shenanigans necessary to seed the generator with the epoch
# time: $(date -j -f "%a %b %d %T %Z %Y" "`date`" "+%s") does nothing
# more than return the current date in epoch seconds, which we use to
# seed the generator. This generator is due to Knuth, and cited in
# Numerical Recipes in C, chapter 7. It's fast on old 32-bit machines
# but not a very good RNG:

      # 6, and I need this for the day_label in question, but I *also*
      # need to know the x-coordinate at which to draw the label. What
      # I would like in this SPECIFIC case, is a loop construct that
      # somehow yields the day_label and x-coordinate, perhaps as a
      # pair, which I guess I could do with a map. But in general I'm
      # looking for a loop construct that accepts n-dimensional inputs
