Microsoft has made available a package of sample master pages compatible with the Application Templates for Windows SharePoint Services 3.0 to showcase some of the customization options master pages provide. The master pages were built using new CSS and Master Page editing tools within Microsoft Office SharePoint Designer 2007.

I have created demo pages using each of the master pages (there are also 5 colour versions of each master page).
