I have a bit of a graphics background (a major that was 1/2
computer science & 1/2 photography), but I don't really
think that relates too much to this. while I think that
your idea of graphically illustrating a program is
interesting, I don't really think that would contribute
that much to a program.
I've seen programs diagramed as flowcharts illustrating the
different steps a program takes while executing, which is
certainly useful for some.
It's not as good, though, as a good design for your
program. Good abstraction, elegant algorithms, and
well written code will, in my opinion, do far more to make
a program easy for someone other than the original author
to understand than all the flowcharts in the world. Those
same 3 things are pretty much my only criteria for the beauty of a program.
Personally, I think that stuff like
tux poster is ok, but not that pretty to look at. I'd
rather judge how beautiful code is by 1 set of standards &
how beautiful a illustration or painting is by a completely
different set of standards. I know a lot of stuff has
tried to merge the two (like the
antitrust movie desktop wallpapers) but it seems silly
