This is just the plain black Vista background with the windows logo replaced by Ubuntu's.
I did not create the used Ubuntu logo or the windows background.
UPDATE: Hmm i noticed some *anonymous* person complaining about the wallpaper being like vista. You may not have realized this but it's not like I'm making you download it. If you don't like it don't look at it. I know that might be a difficult concept but please do your best. (that goes for EVERYBODY)
