Oooh yes, Duke's E3M4 has a building that imitates the appearance of id Software's headquarters and there is an earthwuake when you approach ;)

I've seen videos of RAGE's Quake egg. It's a recreation of the Introduction's first room, though the sky is frozen in place.

Do you know of any references outside games... from movies, for example? On Wikipedia I read about a Shub-Niggurath reference in some book, which is based on Quake's Shubby.
