It think I`d be glad if I could find that artbook in english or german somewhere...
I found two additional links to blame sites:
http://www.cyberiacafe.ch/Tsutomu/Blame/ a little summary and some pictures and artwork
http://www.studiokrum.com/blame/blamepag.html site dedicated to Nihei Tsutomu in general though most is about BLAME! of course
http://www.teamdiska.de/blame/index.php <- some blame forum i came across... seems to be not very crowded, last post is from 2 month ago
So if you want to talk about blame, better do it right here.
