A Tour Of Ancient Rome

We've covered the Rome Reborn project before.  This 13-minute Khan Academy piece (they do great instructional stuff, by the way) uses that project's computer simulation of the ancient city as the basis for an entertaining and educational tour and explanation of how the city operated at its peak.  There is a particularly interesting section near the end on the Pantheon.  The only error I detected was a strange reference to the Washington Wall when the narrator obviously meant the Washington Mall.
