I happen to be working on something similar at the moment, but my shape is made
by a rather brute-force method, not as elegant as yours: Using eval_pigment to
'trace' some high-contrast black/white artwork-- line art, really-- then using
the found white colors as position indicators and on/off switches to place LOTS
of spheres side-by-side, to look like a sinuous single object.

I like your sweep-spline approach better, as well as the fewer chosen points
along the profile, which is more efficient; I may have to 'borrow' that idea.
