An interactive 3D film about a theory of the construction of the Great Pyramid of Khufu in Egypt, first presented to the public in a 3D theatre in Paris, has now migrated on to the home desktop.

To watch the film, one has to simply download a plug-in and don a pair of 3D glasses – although the software gives the sensation of depth without them too, to a lesser extent.
