Run "sudo file-roller" and open the archive. Extract it to the path: "/usr/share/themes/" Done.
You have to select the theme via the gnome-appearance-dialogue and select edit. There you are able to select the theme.
80 % of the theme are from bisigi, 10 % are for lassekongo83's nautilus.rc and 10 % are for my modifications.
I thought I should share it, but don't rate it down cause it's a modification.
Anyone, who has errors to use the theme should read the distributions help page or read the Theme-folders permissions. I am not going to give help.
