If you like dark themes, you may like this one. I find it easier to focus on the work at hand when the surrounding area is black and my workspace white. If you like the buttons, scroll bars, etc, they're from the Domino KDE theme style. The start menu is done with KBFX. The buttons in dolphin are standard in KDE, just normal multimedia play buttons. The whole theme, in general, was mostly inspired by the Kore suite. This theme may require tweaking depending on other themes such as your firefox theme or domino color scheme.

My desktop is also inspired by Vista since I'm a new linux convert, it's more familiar and I find a long taskbar more efficient with work and screen real estate than a taller OSX-like dock. And also to show you, if you want it, KDE can look any bit like Vista and much better with a lot more customization for looks and efficiency to suit your taste and work habit.
