Tux Machines (TM)-specific
A long time ago I was messing with xscreensaver and found you could paint the root window — the desktop — with a screensaver, and use it like an animated wallpaper image.
Most of those were fun for about 10 minutes, but there were a few I liked, and popsquares was one of them.
I was experimenting with them on the Thinkpad today, and this time I set popsquares to use Tango colors, which gives it a more Clearlooks-esque color sequence.
