Destination America: Cheating Vegas Episode on Aria Security

I saw this episode the other day, and it's interesting. Seems the place is so saturated with cameras, that they can use computers to paste the footage together and do the kind of virtual fly-through POV surveillance you used to see mocked-up on the old Las Vegas TV series, or even CSI. The good news is that it requires so much CPU horsepower, that it can only be used after the fact and not in real time.
