A major project called Rome Reborn is a virtual tour of ancient Rome. According to this article an international team of team of archaeologists, architects and computer specialists from Italy, the United States, Britain and Germany have created the most complete virtual reality simulation off Ancient Rome yet. This ten year project was started at UCLA and not resides at the University of Virginia. This is a pretty cool example of the sort of technology that is being used in computer games to provide three dimensional movement in a more academic educational context.
The technology being used allows for relatively easy updates as new discoveries are made. I would expect that models like this would themselves be a way to try out theories and verify that they are in fact practical and correct. Pretty cool stuff if you ask me.
