	All you need is on you *nix box already:


$ crontab -e
5 * * * * bash -c xsetroot -display :0 ~/pix/$RANDOM.xpm >/dev/null 2>&1
:wq

$

	That way you instruct the cron daemon to call bash every five
minutes. Bash will call xsetroot and tell it to draw a random picture on
your background (the $RANDOM variable contains a random number generated
by bash). The output redirections are required since i doubt that you want
to get mail each time cron tries to run this command and X11 isn't up/not
owned by you.


	Well. Looks a but old-school-unix-hackish. But a) Damnit, UNIX 
rocks! b) Someone might write a little GNOME-GUI to maintain this crontab
entry. (Guess the crontab entry should point on 
/usr/lib-exec/my-wallpaper.sh then).


	Disclamer: Don't know if this works when nautilus 0wnz the desktop
background.
