Blender 3D and Geometry Nodes zone

A zone with tips and examples of 3D modelling in Blender. Nearly all examples are about parametric (aka procedural) modelling using Geometry Nodes.
Have you discovered Blender Animation Nodes? It is now for all intents and purposes obsolete you should be looking at Geometry Nodes instead!
Dr Darren explains:
If you like me are into generative (parametric, procedural) modelling and couldn't give a hoot about fiddly "manual" 3D modelling - and if you have previously been discouraged by the historically notorious GUI of Blender - Blender Geometry Nodes may be for you. It's just brilliant. The patch GUI is great, and it has a super and easy to use mechanism for creating sub-patches reusable between projects as assets. And it has some cool features for collapsing wired up nodes to keep your patches clean. The integration with the rendering engines is good, and on macOS Blender5 has ProRes support including ProRes 4444 transparency.

AFAIK the people who contribute to Blender don't get paid for their time. I am most grateful for their contributions.

However, and it comes with the territory, one of the issues when learning Blender is the lack of clear, accurate, well explained, and version relevant documentation and instructional videos. Some of the instructional videos offered up by well meaning Blender users are just awful, it can be painful wading through them to find out what you want, and it never ceases to amaze me how some people who are dealing with a visual medium have such awful visual presentation and sometimes such poor audio you can barely understand what they are saying.

But there are exceptions. There are some contributors who do understand how to make educational videos, and you can even actually see the patches and nodes they are talking about in the videos as you watch their videos (instead of someone chaotically scrolling about mumbling)! Many thanks to those video makers!

Longer term, one aim of this zone is to collect links to the best of the instructional videos, so you don't have to wade through them all for hours.

Feeling brave? Try this! Many of the scenes in this Maths Art visuals video were created using Blender (some uses Wolfram Mathematica) combined with FX:
