Sanya is an WIndowMaker theme rougeley based on ideas I saw on mockups from the etoile project.

It tries to be elegant and inobstrusive while staying visually appealing.

For the shadows use xcompmgr:
xcompmgr -c -C -r 8 -l -12 -t -8 &

I assume most people will replace the wallpaper, I'd recommend grayscale or dark purple wallpapers to fit the tiles.
(If theres enough interest I might create some additional colored tiles).

Please leave some feedback.
Yours, Daniel
