For those of you running Gnome from the Armel repo's here's a link too a deb with plently of extra themes for you.
Gnome Themes Extras (Its an any architecture file - so dpkg -i <name> and its all cool.
Also just from experience, do not use the gnome-volume-control applet ... it seems to cause the gnome-settings-daemon to fail on load. This is not cool, just so you guys know
Have fun.
