I wonder how hard it would be to read a font and create a function whose 
value is zero (or negative) outside and "distance from boundary" inside. 
  Or, as long as I'm wishing for a pony, the function should have a flat 
maximum along the midline of each stroke.

What I have in mind is a round version of the "GEB" jigsaw monogram, 
using isosurfaces.
