I've half-written a couple of whizzy graphics programs -- you know,
the sort of thing that people who take no pride in uselessness prefer
to dignify as a screen-saver. They're all version-zero software,
they're crotchety old code that wigs out on a lot of current graphics
hardware, and I really ought to modernize them and clean them up some
day. Since that isn't happening, here they are.
