[Haskell] ANNOUNCE: Program to set the GNOME desktop background picture randomly

I've just uploaded gnome-desktop to Hackage. This periodically picks a random picture from $HOME/Pictures, and sets it as the GNOME desktop background. It does this periodically. As a result, I now see a different beautiful picture of a dragonfly every 30 seconds, without needing to wait for the screensaver to kick in. Timings and directory can be set on the command line. -- Colin Adams Preston Lancashire
