Rotate Alternating Polylines in Grasshopper to Achieve Spiraling Effect

[Taylor2 (Taylor)]

Hi There,

I am working on a script where the overhangs in the curves rotate incrementally as they move up the surface. I have the script to the point where I have the curves, and the overhangs I want, but I haven’t been able to figure out how to separate the curves and have them achieve the spiraling effect in the image attached. Could anybody help me with this please?

You can rotate the curve seams in the first place.
