This is a world map in Albers projection w/ the center of the parallels at 11.5,-38 I think that means the cone like projection thing intersects the earth at these lats.
One thing I couldn't figure out was how to fill the background of just the projected data blue. Oh well I think I want to hightlight some of the cities where they'll be playing the world cup now....
