Edit: I did not make the cartograms shown below. I found them on the site of Mark Newman from the Univ. of Michigan Physics Dept. His site has had 500,000 hits this week, and he included an FAQ, as well as a link to the free software he used to make these. If I get any data, maybe I'll try to make that education map that Darius mentioned. I've been curious about that variable as well.
