I just noticed that, at Bill Tiller's web site (
http://www.billtiller.com), he has some never-before-seen art from The Dig on display!
In particular, look at Brink's hand trapped in the crevice and the split-open rock or life crystal. I don't recall ever seeing those in the actual game....but I could be wrong.
Also, the air lock screen looks vastly different. How weird.
Maybe we ought to ask Bill if we can put those on the site.
