NOTE:

The Blender version needed to run a specific file is mentioned in its filename.
Most files were made with Blender 3.4 stable version.
But a few of them need Blender 3.5 Simulation Nodes Branch (Experimental) to use them.

A number of node-setups are "pinned" in their Geometry Nodes/ Shader Editor window. This is done so that other objects can be selected without losing the active nodes setup.
