I completed the categories and added some apps....
This is my new Icon theme for gnome.
It is called Sphere 1.0 from the apps icons who are like spheres with metal and glass. It is inspired by the windows icon from D.Arneaz.
The most icons are 256x256 up to 400x400 px (actions are 128x128). I use it with gnome 3.
The work is still in progress, i will make more icons soon.
If there are lots of good comments, i will upload the psd files for gimp, then you can create your own icons.
Enjoy (and sorry for my english..)
