So, right now I have two desktop wallpapers that I alternate between, with very Christmas-y settings in my window manager (Emerald, for those who wonder)

The three images are:
"Studymutt", by  Fluke ( http://www.furaffinity.net/view/928831/ )
"Cuddle", by  Zlodey_Lkk ( http://www.furaffinity.net/view/344204/ )
And a wallpaper of Nanase and Ellen created by Dan Shive, of El Goonish Shive fame: http://www.egscomics.com/

I'm still working on all the settings for the window manager (see how the close button is a fireplace? It animates on mouseover!), so I'm not letting anyone else have it right now. Maybe after I change all the buttons, though...
