Here's a groovy little information visualization (hat tip to infosthetics),
a collaboratively generated geographical map of the US that visualizes how the country is organized culturally, as opposed to its traditional political boundaries. the map attempts to show how the country is divided into 'spheres of influence' between different cities at the national, regional & local levels. in practice, it is based on the collective 'votes' from thousands of users about which city they belong to, what they consider to be their local area & which major city most influences their area, as well as their life.
You can cast your "vote" over at their site, commoncensus.org.
Me? I just like the pretty colors...
