In partnership with IBM, The Supreme Council of Antiquities and Center for Documentation of Cultural and Natural Heritage have unveiled their online multimedia masterpiece, Eternal Egypt. The site is also available in wireless phone and PDA formats, features text-to-speech commentaries, and 3D views of famous monuments and sites, such as Giza and Luxor.
For budding Egyptologists, I also recommend the Theban Mapping Project, a Flash site developed by the American University in Cairo to map out the Valley of the Kings.
Eternal Egypt runs on DB2 over Linux. The TBM runs on Access over Windows 2000. However, both sites hope to preserve the past through technology.
