Pyramid scheme  Dassault Systèmes, a French software company, spent 5,000 hours creating a 3-D computer simulation of the construction of the Great Pyramid. The animation is interactive and allows the visitor to rotate, zoom in, out, and fly over the site. The result is breathtaking. You’ll need to wait a minute or two to download viewing software, but it is well worth the wait. The simulation visualizes a new and thought-provoking theory on the construction of the pyramid. Read our article about the genius behind the theory in last winter’s issue of Cram.
