Here is a message I sent to Guido Berhoerster and his reply.
I am a fan of the Windows XP Royal Noire (skunkworks) theme, and was surprised and excited to see it as the default theme in OSS 13.1 LXDE. I have given up on Gnome 3.x, as I have given up on Windows 8.x. I have found XFCE to be a suitable replacement, but with a convoluted windows, dock and theme structure. (Forgive my senility, I keep comparing everything to WinXP).
Anyway, I believe Guido said the engine is Aurora and the theme is nuoveXT2. I still call it Royal Noire. Have a look at Guido's comments. Perhaps if others are interested the Royal Noire theme can have a new life in Linux/BSD's.

* Tas Papadopoulos firstname.lastname@example.org [2013-12-11 22:59]: Hello Guido:
I noticed that you were both on the OpenSUSE LXDE and XFCE teams. I love the LXDE OpenSUSE theme in 13.1, which ;) looks like the Windows XP Royal Noire theme. Do you think there is any chance of porting that theme to XFCE?
I'm using XFCE in lieu of GNOME 3x which I don't like. Perhaps you have some advise on LXDE versus XFCE?
Thank you very much and wish you the best for the holidays,
if you mean the GTK (toolkit) and icon theme, those do not need to be "ported" to Xfce, you can simply install the gtk2-engine-aurora and nuoveXT2-icon-theme packages and select the nuoveXT2 icons and Aurora style under "Appearance" in the Xfce Settings Manager. The problem with the Aurora engine is that it is a GTK2-only theme, newer applications using GTK3 will not be styled and get a rather ugly default look. This is the reason why we use Adwaita as the default theme, it is one of the very few theme engines supporting both GTK2 and GTK3 and thus providing a consistent look for all GTK applications.
Also, please send such questions to the openSUSE Xfce mailing list (email@example.com) rather than via personal mail.
