Alex_J8y_Feingold There are many beautiful designs related to knots and topology. Compare this with two of my designs, the Tubular (3,5) Torus Knot, and the Mobius Figure Eight Knot, which can be seen in my shop: as well as the work of Bathsheba Grossman and Henry Segerman.

Hyperbolic paraboloid
Alex_J8y_Feingold Henry, Thanks very much for your prompt reply! I'm in the middle of some other work, so there is no hurry about this question, but I would really like to see an example of how you incorporated a Python script into a Rhino model. The best I could manage was to use Mathematica to calculate some points on curves, output their coordinates as text, and input that text as a set of points into Rhino. That allowed me to get the curves accurately into a Rhino model. Surely you had a better way to get the quadratic surfaces you made! I greatly admire your designs!
Alex_J8y_Feingold Henry, Do you know if the Mac version of Rhinoceros allows a scripting interface of some kind (Python or Mathematica or ...) ? I thought that Grasshopper was the only way to get programming to interact with Rhino, but that has not been done at all for the Mac version. Thanks for any comments.
