This is my KDE4.2 desktop. Which I find very clean and tidy.
Bespin for widget win deco
AThemeInANeedOfAName colour style
Bare Naked as plasma theme (my very own)
And XBar to get the OS X like universal menu bar
Hope you like it.
And if you do please try Bare Naked and comment on it.
/a bit of self promotion never hurts ;D
