I have added the new Falloff Tracer node in the Animation Nodes + Extra Nodes for Blender. This node allows to trace any falloff like a field with Curl and Gradient methods in 3D space or on the mesh surface. The Curl method gives results similar to a Curl Noise. I hope you like this tutorial 
Project files in the video description.
Happy Noding …
That looks very cool! I definitely want to give that a try when I get some free time!
Thank you 
What is the latest stable version of animation nodes for blender 2.93??
The latest version of Animation Nodes and Extra Nodes is v2.2. Here: https://github.com/3DSinghVFX/animation_nodes/releases/tag/extranodes-cd-build
In the add on panel it still says " this addon still in development". Is it okay?
And thanks for the addon mate.
This is the latest version which is under development. We are planning for the release 
Great. one last things for 2.92 version the AN 2.2 does it have extra nodes like latest? Or can I use the new version you suggest in 2.92??
The Blender 2.92 uses Python3.7, so you have to use AN+EN v2.2: https://github.com/3DSinghVFX/animation_nodes/releases/tag/en-v2.2-for-blender-v2.91-v2.92-cd-build
However, for Blender 2.93+ uses Python3.9, you can use the latest version of AN+EN (that I mentioned before).
Great. Thanks.
