i saw this one on somebody else's computer and just wanted to have it :)

start it up in a small window and then resize to full screen for
complete satisfaction...

it doesn't take all that much to convert the X drawing calls to draw ones,
took me longer to clean it up into some sort of viewable form. i'm sure i
haven't managed to do so completely.

non-plan9 code is GNU, so have that in mind if you decide to play with it.
