[FRIAM] Great Circle

These are fun.  If you  extend the shortest route from Charlotte to Honolulu you end up  in New Zealand.   But if you look for shortest route from Charlotte to New Zealand, it is essentially [slightly sigmoid] straight line passing through Central America.  And if you look at the route from NZ to S. Africa, it’s a Walmart happy face with it’s chin on the coast of Antartica.

The basic insight is that the central limit of random walks from any point in a soap bubble (whose surface is a harmonic potential function) to the boundary will generate the harmonic function.
