Cartograms got a lot of coverage in 2004 when Michael Gastner, Cosma Shalizi, and Mark Newman used them to show the Bush/Kerry election results. Naturally, they've put together a similar series of (very red) maps and cartograms for the just past 2008 election.
In case you're unfamiliar with cartograms, they're essentially maps with morphed areas according to some metric. The election series for example are adjusted for population, so that states are sized by population instead of physical area. The drawback of course is that after a certain point, the image starts to look a lot like a Pollock painting.
