Seems I still have a need for openbox after all so couldn't resist one last style. Included are configs for openbox, gtk2 (just a re-coloured Absolute theme) and tint2. And for QT apps, just use the standard Plastique style.
Openbox is a free, stacking window manager for the X Window System, licensed under the GNU General Public License. Originally derived from Blackbox 0.65.0, Openbox has now been totally re-written in the C programming language and since version 3.0 is no longer based upon any code from Blackbox. Wikipedia
