I was working with a couple of students on cellular automata, and
thought I'd share the file I used to create the 1-dimensional
(elementary) version (see PTSF for my code and see
http://mathworld.wolfram.com/ElementaryCellularAutomaton.html for some
explanation.
The images are nothing special, and they don't compress very well (by
their very nature), but I included 2 anyway. It is somewhat instructive
to color the cells according to the state of their neighbors. This
allows you to anticipate the next generation, and see the rule better.
I've use the convention:
rgb <state_of_left_neighbor, state_of_cell, state_of_right_neighbor>
so that any cells with green in them (green, yellow, blue-green, white)
are "alive."

Hadn't thought of that, but now that I tried it, the 94 K one was only
reduced to 88 K (at 256 colors.) At 8 colors it was 33 K, but barely
identifiable.
Normally I just use jpeg, unless it's something obscene or
controversial, when jpeg2000 is the traditional choice ;-)

Then try png, it should be even smaller...

Have a look at this:

I managed to get it down to about a 33K gif without a huge reduction in
quality, though still noticeable.
