A nice shiny glossy Windows XP logo! I had initially just made this for myself but I got many requests for it after I posted my desktop, so I made a few colors variations and will post it here. I know it's not a very original subject, but it's just for fun.
The zip contains 15 variations, various backgrounds with a black logo, some with a multi-colored XP logo and some with a Longhorn colored logo.
There is also a 1920x1200 zip available for those with wide screen displays.
EDIT: Just wanted to note that the bottom row of color variations is only for the preview and does not actually appear on the individual wallpapers.
