Perhaps I am too contrarian, but for me the scaling of the thorns near the center strikes me as being too “natural” - we see this sort of structure in nature all the time. I prefer keeping everything the same size:
This gives a much more un-natural look that I think makes sense for computationally defined objects and structures.

I haven’t looked at your GH file but isn’t that what I did yesterday in version ’ Aug14d’?
When I did the spiral (version ‘Aug14e’) where points are closer together near the center, scaling was required rather than artistic. Like it is in the natural world.

Indeed it is. For some reason I missed seeing that - probably by not scrolling back far enough.
The teal group at the bottom creates “spiral arms” as branches by selecting every third item with Series starting at 0, 1 and 2.
Wow, I’m also a GH noob and this is some wild stuff! Really appreciate the 3D printing links too. Many of these patterns remind me of the old Spirograph drawing ‘toy’.
