I've been watching it for a long time, now. The short story is: talented and daring photographers go into sewers, abandoned property, and other places they probably shouldn't be and bring back pictures of the fantastic landscapes they find there. I like to use them as inspirations for some of my stories, and realized that many of the photos I see are pretty darned steamy. It's easy to imagine a lot of them as being taken in a mad scientists lab, the tunnel of an underground complex, or (especially in this entry: http://community.livejournal.com/urban_decay/2253763.html) the streets of a steam-punk city.
Just thought ya'll might be interested.
