A Miner3D sitemap
To see this sitemap, you'll need to have the free Miner3D plug-in installed from Miner3D.com. It's only 85K and it enables you to view text-based 3D environments that are coded in XML, making them quick to download.
This demonstration shows a small sitemap. All the links are active, but it doesn't represent the whole of this site. You can click in the window and move the mouse to drag it around, and you can double click on the boxes to go to the appropriate webpage.
