Hi Brian,

well, that question can only Michael answer. :-)

But the Grasshopper link, with it's examples, looks very interesting!
Thanks for providing the link!

I wonder however what export formats Rhino/Grasshopper uses
to save the edges? I know from Surface Evolver that Evolver files
uses edges to describe a model. The coloring of vertices, like shown
there, is possible with .obj and others.
