Vector Flower Patterns Theme
This pleasant Windows theme provides five high-quality floral wallpapers and turns your window borders a nice rose color. That's pretty much it... the theme uses Windows default sounds and doesn't affect icons or fonts.
Installation is simple; just download the themepack file and double-click it to launch the Windows Personalization dialog box. You can customize the theme by selecting how long each wallpaper will appear in a slideshow, or choosing just one to use.
If you want to dress up your desktop with some original artwork rather than canned Microsoft themes, give Vector Flower Patterns a try.
