I`m aware of the Themes avaiable for OS X (I like non of the few themes for either Kaleidoscope or the new project for OS X).
I just wanted to point out that with all the 3rd party devolopers using lousy Aqua-esque designs (Omni Web, WindowsMedia player for OS X etc. etc.) it`s getting to much.
It looks silly and cheap and the workplace looks like a playground.
