Prisoners Inventions

Speaking of prisoners' resourcefulness, there was a piece on This American Life about a book called "Prisoner's Inventions." It's a collection of inventions by prisoners...hence the name. The radio piece is pretty good (check out part two of the archived version), but there's also a website with photos and descriptions that never made it into the story. See how they make chess sets and cigarette lighters in the big house. I guess they have nothing better to do.
