Notes:

All themes displayed are xhtml and css valid except for some vendor specific prefix css 3, used on some of my themes, that don't validade as W3C standards and IE will not render them, so be sure to let your users know that for better performance they should use the latest Firefox, Chrome or Safari for better visualization of these themes.

As for the looks and code, i consider them generic starting points to build on if you're interested in customizing your own.
