I just found a nice icon theme that others will probably like, its based off of the KDE Oxygen Theme ported over to gnome by Chris Smart
tar xvjf oxy-gnome-080504.tar.bz2
mv oxy-gnome ~/.icons
Alternatively you can install the icons globally by moving the icon folder:
sudo mv oxy-gnome /usr/share/icons/
Right Click Desktop->Change Backround->Theme->Customize->Icons->Select oxy-gnome->Close
Let me know what you think, also if you know of any other great icon packages let me know and I'll feature it here giving you credit!
