I didn't find anything else similar to this, so I'll put here. I made a few themes for Cinnamon 1.8 desklet called "CobiAnalogClock". Themes are pleasant especially for darker wallpapers (except for KDE like theme).
All themes must be placed in your home location /.local/share/cinnamon/desklets/analog-clock@cobinja.de/themes/

Enjoy and give comments.
12.09.2013 - I added some new themes that I made earlier, but I forgot to put here.
A total of 9 themes (not including the default theme)
