Best?!? Slowest and most likely to produce artifacts, if it works at 
all...isosurfaces don't like infinite gradients.

Don't know what you mean by "grooved" here. If you mean an engraved 
appearance, the object pattern as a normal could work, the normal will 
be perturbed at the boundaries of the object pattern. Or you could use 
the pattern blurring techniques to get smoother transitions on the 
edges, povray.binaries.scene-files has some work on this.
If a texture won't do and a real object is needed, the best thing would 
be to construct a union of the individual letters rotated into a 
circle...the Circle_Text() macro already does most of this, you just 
need to modify it a bit. If you need the outer surfaces to be curved, 
just intersect it with a cylinder.
