Rob, playing with the ideas of George Monbiot, put together a nice visualization of a district map for a “global parliament”, a proportional representation body to balance the 1 country, 1 vote UN model, a House of Reps, to the Senate as it were. I think the model is problematic, but its a good tool for exploring what a global democracy might look like.

(disclosure: I totally failed to help Rob come up with a clever algorithm for doing data smoothing over a set of 20 million cells. What can I say, I was a Comp. Lit major)
