The cover art for this book by Hermann Weyl http://www.amazon.com/Open-World-Hermann-Weyl/dp/0918024706 shows the surface of the globe conformally mapped to a flat torus -- the singularities are cleverly hidden in the oceans. Veit On Jan 23, 2012, at 11:44 AM, Fred lunnon wrote:
I'm intrigued by the blank circles in images on right-hand side: it looks as if he has some way of mapping multiple hyperbolic infinities to a lattice in the plane, suggesting a (2-D) space peppered with black holes of varying masses.
If the tiles were now blown up back to congruence again, what shape does this space have: eg. is it describable by some simple metric?

The art work for this one was hellishly hard to simulate. And I even didn't reproduce M.C.Escher original woodcut detail - half of the angels and half of devils are actually looking back.
