Now that the Windows 7 public release is just around the corner, people are getting into the spirit of celebrating the new OS by releasing their own unofficial but very cool Windows 7 logoed wallpapers and theme packs. Using the Windows 7 box art for inspiration, Zawir Rahim over on DeviantArt created a wallpaper pack featuring the Windows 7 branding in a number of HD images (1920 x 1200) in all colors of the rainbow. Redmond Pie then took those individual wallpapers and packaged them into 15 different theme packs for easy one-click installs. (Download here – zip file).
Next, over on Life Rocks 2.0, they've aggregated 35 of the best Windows 7-inspired wallpapers, also from DeviantArt. This collection includes creations from several different designers and many unique styles. To download those wallpapers, there isn't a single zip file - you'll have to click on the images and then grab them from the DeviantArt site itself.
While you’re at it, you can also head over to The Windows Club forum and grab some unofficial Bing wallpapers, too, created by the community members.
