OpenOffice without Gnome of XFCE

Problem: OOo looks just ugly (no skins, no themes etc) while running in Openbox and other not so Gnome'ish desktop environments.
Solution: Run OOo with environment variables set as:

OOO_FORCE_DESKTOP=gnome

Note: In KDE variable value should be changed to 'kde' instead of 'gnome'.
Packages like openoffice.org-[gnome/kde/gtk] need to be added for this feature to work in some linux distro's.
gtk-chteme package is also a good choice for changing GTK themes apart from Gnome Control Center.
