I've always loved maps, and in particular the different ways they approach the problem of emphasizing certain details like shape, area, topography, or human impact. That's a problem because, in order to emphasize one thing in a map, you have to de-emphasize something else: blatant distortion of reality in order to get a point across.
I've wanted one of these south-up maps ever since I first saw a similar one nearly 30 years ago. I finally gave in to temptation and got one from ODT Maps; it just came in the mail yesterday. I can't wait to think up some assumptions to challenge.
