Trip the Blight Fantastic
Check this out--some guy built a super-detailed, urban decay-filled Bronx model railway. How detailed? Well, you just about expect to see a buncha inch-high mobsters saying "Fuhgeddaboudit" running between all those tiny, graffiti-covered brownstones. I lack the kind of uber-focused nerdiness necessary to pull this off--as well as, let's face it, basically zero interest in model trains--but if I did, I'd love to see somebody do up Liberty City like this.
