Dymaxion Projection Globe
I was reading up on cartography earlier today (via O'Reily Radar) and read a piece on Buckminster Fuller's Dymaxion projection technique. It's a pretty interesting application of the Bucky-Ball and I decided I'd print out a satellite image projection and fold it up and make my own.
When you first see the laid out projection, it doesn't appear to be a regular shape at all. However, several of the 20 triangles are cut up as to keep land masses together on the out projection. It's an ingenious solution in cartography and another great use of the Bucky-Ball polyhedron.
