Tetrahedral pseudoglobe, Lee's conformal projection

Tetrahedral Pseudoglobes

The tetrahedron is the simplest regular polyhedron, and by far the easiest solid to render in paper. With a low face count, its shape departs a lot from the sphere's: distortion is very noticeable, especially with gnomonic maps.

If you have never built paper models, please read the general assembly tips.
