Looking for a large one for the wall. The facing wall has a great map of the Earth, 1 meter tall by 2 meters wide, two seperate hemispheres in a stereographic projection.
Stereographic projection preserves circles and angles (the image of a circle on the sphere is a circle in the plane and the angle between two lines on the sphere is the same as the angle between their images in the plane).
Would like to see the same for Mars. Before we had good cartographic data, projections used on maps were orthographic, just a view of a hemisphere from near space, but the projection preserved no properties of the area being mapped--- not equal area, equidistance. If anybody remembers the popular Mercator projection in which Greenland was shown as larger than South America (S.A. is actually about 9x larger), you can see what I'm getting at.
