It was a modification of Industrial I did for myself. I've put my entire ~/.themes/Industrijska/ inside a tarball at http://kvota.net/hacks/Industrijska.tar.gz (Metacity theme doesn't work for me anymore). If you clean it up and find it useful, I'd like to hear about it :)
The thing I hated most about this was that the Gnome menubar on panel appeared in lighter colour, so I mostly used "Foot menu" instead of menubar on the panel. That can probably be resolved as well, but I don't know how exactly. — Posted by Данило at Mon Dec 13 11:11:54 2004
