Powered in a different way than Platial's people-power,Worldmapper has added some new countries to their maps showing country shapes distorted by population. Worldmapper has a lot of cool mapped data visualization. It is well-worth checking out. They have free PDF posters designed for printing, of all their maps, plus lots of other ways of using them. I would love to have a high-quality hardcover book of their maps for my coffee table.
