2 options: Blue and Black.
Includes metacity themes too.
Note: Packaged this one in 7-zip to reduce the filesize a lot. Install 7-zip support with your package manager. Fileroller should be able to open it after that is done.
How to use the start-here.png icon:
Put it in your current icon theme's Places folder and backup+remove any icons that are named start-here.svg/png. Your icon theme should be located in /home/username/.icons/.
If you're using an OS default icon theme you may need to open the gconf-editor and select to use a custom application icon in the applications-menu.
After all this - Terminal > killall gnome-panel to refresh the panels.
