             I'm hoping someone has already done the math on this one.  I know that it can't be solved perfectly, but close would be nice. Suppose I have a sphere, it's covered in square pixels.  At the equater there might be 360, at the pole 3.  Now I want to address each pixel in a 2-dimensional array so that I can calculate a reaction-diffusion equation on the surface of a sphere.  This equation requires consulting adjoining pixels. Can anyone give me a place to start, my math is very weak.
