Internal Pyramid Ramp

Now that nobody else is visiting the site, I managed to download and view the information at http://www.3ds.com/introduction/.

It is pretty much 90% gloss and 10% theory. Would have been much better (and more profitable) as a book, but they seem more intent on promoting 3ds.com.

On the face of it, the theory has great merit, probably the equal of the concrete theory, and I wouldn't be surpised if a physical exam (or scan) found that the internal ramp exists - although it has almost certainly been filled with rubble.
