Yes, you are probably right. - But first I'm curious about what has already been
done with L-systems.

I don't know if this reprint (or new edition ?) "The Fractal Geometry of Nature"
book by Mandelbrot contains any L-system images/rules:

https://www.amazon.com/Fractal-Geometry-Nature-Benoit-Mandelbrot/dp/1648370403

If so then I'll have to consider buying it.

Yes, I remember his crazy plumbing work. Very fascinating. I really miss his
wonderful art in here.

When I replaced macros with functions in my L-system library I tried to make it
so that 3D functionality could be added later without much redesign.

But I'm not sure how the rules should work in 3D. Have you seen any such
images with accompanying 3D rules? If so, that would help me understand what is
needed.

No worries. I'll add a Hilbert curve example as you suggested.
