Hi Thomas,

Nice job working on some simple "planar" surfaces.

I thought I'd point you to a few links that might help and inspire you in your
future work.
I like the flattened-sphere method that you're using from a simplicity
standpoint, however I would suggest that triangles or smooth_triangles might be
almost as simple, yet give you a smoother, more continuous surface.

For your splines going across the surface, perhaps a Bezier patch would work
best, with a sphere sweep for the splines.

Considering your interest in modeling nature, I don't think you'd want to miss
out on Friedrich Lohmueller's excellent leaf modeling tutorial.

Hopefully this will inspire you, and I'm looking forward to seeing what you do
with all of this in your next full-length video.
I think that you could make an excellent lipid bilayer or something similar!
