Experience ancient Rome in 3D

A team of international technology experts has created the world's biggest computer simulation, a model of the city of Rome at the time of the Emperor Constantine.

"This is the first step in the creation of a virtual time machine, which our children and grandchildren will use to study the history of Rome and many other great cities around the world," said Bernard Frischer of Virginia's Institute for Advanced Technology in the Humanities.

The project used 7,000 buildings to produce the 3D model of the city called Rome Reborn, a project which has taken 10 years.
