Kinetica - Trace in Geometry Nodes
A pure GeometryNodes setup of a "kinetic sand art" effect, with a custom carve object following a user defined curve. This custom "Carve object", here a sphere, displaces the sand grains along its path, tracing out whatever shape you desire. Since the setup is made for ease of use, you can instance any object on the points, and replace the "sand" to any material you wish to draw within.
The strength and speed of displacement is adjustable. With additional controls included, you can create a "fade effect", where the tracks are gradually covered, the handy way to create loops for decorative interior designs, sci-fi effects and so on.

Compatible with Blender 3.6X and above.
Many version has been uploaded. The base version is "1". Some audiovisual examples added too!

NOTE
- Since it is a concept demonstration, it is kept as simple as possible. The GeoNodes trees are kept clean for easier readability and have detailed explanations. Everything is built from the base. The point of these setups is to provide a base core of the concept, node from node, instead of contracting all into node groups with exposed settings, which makes everything harder to read and dissect.
You can embellish, refine as you wish based on the core or realize your own ideas.
- Read the text description, it has a lot of useful info !
-(The setup should be opened in Blender 3.6X and above)
-The file is optimized for and rendered in Eevee (Render Viewport Animation). Of course, you can set up any renderer you wish.
