NewHuman-Rezlooks is the NewHuman theme from the Ubuntu Intrepid Ibex alpha adjusted slightly to use the Rezlooks engine.
As it goes it's not much of a theme since it's really just the original theme from the human-theme package, with lines commented out that would offend the rezlooks engine. After that, there's no changes to the original theme.
Credit goes to the people at the top of the gtkrc file; I take no credit for any real work with this.
GNOME is an international effort to build a complete desktop environment-the graphical user interface which sits on top of a computer operating system-entirely from free software. This goal includes creating software development frameworks, selecting application software for the desktop, and working on the programs which manage application launching, file handling, and window and task management.
GNOME is part of the GNU Project and can be used with various Unix-like operating systems, most notably Linux, and as part of Java Desktop System in Solaris.
The name originally stood for GNU Network Object Model Environment, though this acronym is deprecated. The GNOME project puts heavy emphasis on simplicity, usability, and making things "just work".
