The projection of the ExtendedComplexPlane onto a sphere such that 0 is at the south pole and infinity is at the north pole.

Here's another good one, which seems to me to be related (wikizens please decide for yourselves, and correct if possible my mistakes).  I have, at work, a function that includes a Dirac distribution.  I have to integrate said function.  The only way I have of evaluating said function is by point sampling it.  A Dirac distribution or function is a function that is 0 when point sampled, yet integrates (over -infinity to infinity) to 1.  Lovely!  The practical application, by the way, is the total light coming from a perfect mirror towards the eye, found by integrating the light coming in from all directions multiplied by the scattering formula for a mirror (which is 0 for all incoming directions apart from the reflected direction).
