This is cool:
An international team of architects, archaeologists and experts spent 10 years working on a real-time 3D model of the city called Rome Reborn.
Some 7,000 buildings were scanned and reproduced using a model of the city kept at a Rome museum.
Users enter the city at the time of Constantine and see inside buildings.
The simulation takes place in AD320, which is said to be the city's peak, when it had grown to a million inhabitants.
So, Rome on HBO was cancelled but it seems we don't need a TV show to feel at home in Rome:
"Talks are said to have begun with Linden Labs to make the entire simulation available on the internet through the company's virtual world Second Life."
When are you moving in?
