OxygenFire is an admin theme using an iconset originally intended for KDE called Oxygen, but many of the icons have been altered to suit.
OxygenFire is a fixed width theme set at 1000px wide. (this can be changed in the CSS of course) Look out for this:
#OxygenFire-container
{
width: 1000px;
}
OxygenFire uses an IE fix from Google that fixes transparent PNGs in IE and other problems. It eliminates the need for an extra stylesheet for IE.
Look here for details: http://ie7-js.googlecode.com/svn/test/index.html
I've included a number of other icons that go in the core modules 'images' folders. (some modules need an 'images' folder to be created) This gives a unique icon to each menu item when you click on the top level nav links.
There is also a folder of my working files, that contains Inkscape SVG files and Fireworks PNG files. These may be useful to someone who wants to modify it.
OxygenFire is based on the NCleanGrey theme by Nuno Costa.

). What I want to say: I think it is very easy to "understand". The extra spacing makes it very handy on larger screens and the bigger items don't require you to target your mouse movements very precisely
