LucasArts has updated their 20th Anniversary Page with some lovely concept art from what appears to be the end of The Dig, though I guess the final product changed a lot between the time that concept art was drawn and the game shipped (go figure, it's The Dig). I haven't played The Dig forever.
Update: A-ha! I think my original suspicion that this shot is in fact from Loom and not from The Dig might be correct after all, after looking at this screenshot from LucasFans. Also you can sort of see it flying away at this site. Heh.
Update: Ok, LucasArts has fixed it at this point, but if you really want to see the goof-up, it's right here.
