I remember seeing something like this when I was using Mandrake 7.1 a couple of years ago...
When I would open an xterminal and a different background image would come every time I opened xterm.
I just thought it might be cool to implement that kind of thing on my current setup. I just don't have a clue how to do it.
I'm running Slackware 10.1 with dropline-gnome 2.10.
Anyone want to clue me in? I know someone knows what I'm talking about
