In the meantime, why don't you check out some cute wallpapers with things I like on them, and a Christmas theme! Yaaaay!
Stitch Wraps Presents - A wallpaper version of one of my favourite Disney stock images of all time.
Keroro's Christmas - Speaking of aliens and yuletide cheer, why not adorn your desktop with Keroro, Tamama, Giroro, Mois and Natsumi in Xmas fettle?
Rudolph And Santa - From the original Rudolph special!
Oddly, there's a huge lack of R/B desktop backgrounds. I honestly don't know why.
