This awesome visual style for Windows 7 was created by DA user "mistraval". It comes with custom wallpaper, custom start button, custom explorer frames, custom logon background, custom metro cursors, and fully styled explorer shell ui. Note that all necessary customization tools are included in the theme package.
Give this theme a try - it is really nice work.
You can use UxStyle instead of UXThemePatcher to add support for third party themes in Windows 7.
