It's a square, square world!

I was browsing for books on elliptic functions on Ebay when I came across this link to a book by Oscar S Adams called "Elliptic Functions Applied To World Maps". This is pretty obscure, I thought to myself, so I googled Oscar. Sure enough, there really was an Oscar S Adams who worked on cartographic projections and his speciality was conformal (ie. angle preserving) projections including this one:

Anyway, there are lots of interesting conformal projections out there. Some of them are quite pretty so I thought I'd share. I like the use of the Schwarz-Christoffel transformation, better known (to me) from 2D fluid dynamics, to map the world into a variety of polygons. I was also surprised to see that Charles Sanders Peirce worked in this area.

Just for the hell of it I might place a bid on the book.

UPDATE: Come on! 'fess up if you're the person bidding against me!
