For years now I’ve been fascinated by Jim Naureckas‘ website New York Songlines. Basically he traces the constantly vanishing history of the city block by block. I don’t remember when I first found the site but I was really taken with the notion of using the Aboriginal Australian idea of songlines as a way of looking at the invisible city.

You know what would be cool? A google mobile app that merged maps, GPS and songlines so that anywhere you were you could automatically know the history of that place, with links and images. Someone out there should know how to do that!
