Urban Archipelago via Google Maps

Seattlest's mothership Gothamist.com found this great mashup of Google Maps and Fundrace data that shows Seattle's 2004 Democratic donations to be about what you expected. Above is a flat image of a random north Seattle zip code (98103), but over at the site you can type in any number of zip codes and you'll get a clickable Google-style map that will let you see the name, address, amount and recipient of donors.
