I seem to recall a Feynman story about "hearing the corners" on the sound of a certain drum, but can't find anything on th'internet; could be imagining it. Anyway, different shapes exist and do sound different: how exactly? There's lots of math on this, and now I see some by Marc Kac, who knew Feynman, so maybe I am remembering right. Check this W'pedia article involving 16-dimensional toroidal "drums." That's trippy.... [more]

MeFi post: Philly in 3-D

These guys don't have a virtual Philly, but they do have dozens of other cities modeled (including a pretty nice San Francisco) and were doing it... 14 years ago?

Also, nobody's mentioned GTA/San Andreas yet in here, another fine example of convincing 3D environments.
