Theban Mapping Project

This is quite possibly the coolest thing I've seen in a long time.

I've always been a sucker for floorplans. I guess it's because I like to imagine myself in them, exploring each room. Even before First Person Shooters existed, I've been doing the FP part of map exploration in my head and yes, I go nuts if there's an incomplete map on my online game.

But this... oh, wow. Not only do you get detailed maps of 60+ Egyptian tombs, you get them in scaleable, zoomable, damn-near interactive views. Isometric, top-down, and various side perspectives are cool enough, but wait until you hear this:

On the maps & plans page you can use a line-drawing tool to measure distance and angle between two points.

If you GM any kind of fantasy game you will crap yourself over this kind of resource. What's shocking to me is that this place has apparently been around since 2003 and it's the first I've ever heard of it.

(Special thanks to Chgowiz's Old Guy RPG Blog, without whom I'd have never found this. I've been quietly lurking on his blog for a bit, but now he's earned my open readership.)
