Here is a spherical Smarandache curve, grafted on to the ElasticaSpherical script.
It is the vector sum P + T version. T+N and P + T + N version also work.
It is an experimental script at present.

Starting with a closed 4 cycle Spherical Elastica, the Smarandache curve does not quite close, even with 5000 points.
The two ends are like two cars going in opposite directions, about to pass each other.
So a small area was trimmed with a sphere, and a blend done.

It is possible to adjust the pSquared decimal values for the SmarandachePT curves so that they have a very small lapover, very nearly in
the same lane of traffic. Then do a small sphere trim and blend.

A 2 cycle baseball curve turned into another curve, that looks a lot like a baseball curve.
