Not sure if this belongs to this thread but I stumbled upon a Hi-Rez 360 Degree Urban Skycam, which offers panoraminc views above Bucharest, with the ability to pan 306 degrees and zoom in and out.. Here's a snapshot of it.
Here's the link from which I took the snapshot, you can play around with it:

I thought this was pretty incredible. Do you know of any other websites that offer urban vistas like this?
Cheers
