Great piece on PS and PDF Nelson, indeed. I have loved ps for years,
but my biggest frustration was not being able of finding a way to
implement a 2D random walk in postscript that would show a different
trajectory every time you open it :D (the only problem there is the
seed). You can hack around with a sed script, but that spoils 99% of
the fun...

Maybe you have a pointer for that?
