“Wallpaper Clocks have always been of great fascination
for me. Unlike many other desktop eyecandy that we have discussed
before, Wallpaper Clocks are quite unique and will work almost like
your ordinary wallpaper in terms of memory usage. If Ubuntu 10.10
customization tips are not good enough you, try wallpaper clocks. A
big surprise is assured.
