This is great fun. Made by Dassault Systems using their own 3D package thing, Virtools, it’s an explorative (to an extent) look at the Great Pyramid and the theories about how it was built. Very nicely done. You do have to download the appropriate plugin which may not be to everyone’s taste but it is worth it
It seems that the best is yet to come however, because when you try to go inside you get some blab about March 2007. Definately one I’ll keep in mind.
