Get into the Christmas spirit by making your desktop look festive with any of the three "Merry Slickmas" themes I've presented here. These themes are all red-and-green variations on TheRob's famous "Slickness" theme that will make your desktop look festive.
The icon theme I recommend with these themes is "Christmas Remix", which can be found at http://www.gnome-look.org/content/show.php/Christmas+Remix?content=115985
If you like to use the Main Menu, GnoMenu, or the Mint Menu as your menu, I've also included customized launcher buttons as well. The emblem on them can be a Christmas ornament, the star over Bethelehem, or a candy cane. They also say "Merry Christmas!" in English, Spanish, French, German, or Italian.
Please let me know what you think of these themes. Enjoy, Merry Christmas, and Happy 2010! :-)
PS -- the file is a 7z file, as that was the first archival file format I tried that came in at less than the 750MB limit here on GNOME-Look.
