I would love to see the scad file for this. I have no idea how you've created such flowing lines.

Let me try to explain. What I did was to define trayectories using Bezier splines, and use them as the center of sequences of spheres whose center moves along the spline. In the sequence, each sphere clearly overlaps with the previous and the next.

In my first attempt this is all I did, and the result was not too good: you could see the chains of spheres. Then I had the idea, instead of using
spheres S1, S2, S3, ..., Sn, use the hull() directive. So we have n-1 segments: hull(S1, S2), hull(S2, S3), hull(S3, S4), ..., hull(S_{n-1}, S_n). This, and a decent value for $fn and $fa, was enough.

Hope it helped.
