Studio KRuM's BLAME!
This is a very nice site with BLAME! translations, art, and extras.
Nice BLAME! artwork scans here.
BLAME! ASCII art and comics - very amusing!
They announce Nihei-related things here.
It used to have some strange BLAME! thing with scrolling text,
but I think that's gone now.
BLAME! translations and others.
Official Web Site, although Nihei apparently doesn't have much to do with it.
Heeen's Blame Forum
Awesome BLAME! message board
