I love opportunities to look at the world from different perspectives. My interest in geography began in elementary school when I unsuccessfully tried to explain to a teacher that having north rather than south be the up direction was arbitrary. I become even more interested when I learned that the popular map formats (e.g. Mercator) were designed by Europeans to make Africa look smaller than it really is (check out the Winkel-Tripel projection for a more accurate representation of the globe). In that same spirit, WorldMapper is a collection of maps on which countries are resized on each map according to various facts. Very cool.
