I'm working on my final project for the year: a look at an extremely large refugee camp that existed on the Thai-Cambodian border from about 1979 to 1993. The camp held up to 200 000 Khmer refugees in a space of about 3 square miles.
In any case, it's not done yet. You can find some good pictures on the Internet in a few places:
But, mainly, I recalled once taking pictures for my student newspaper of this amazing gun sculpture built from 7000 deactivated weapons. You could actually step inside and see bits of light shining through from the outside. But it's the creepiest thing in the world. The gunpowder smell hadn't left it at that point, and it was like standing inside some kind of death. It was just overwhelming. Anyhow, if you ever get a chance to see it, do it.
