This animation makes use of the new Geometry Nodes functionality that was introduced in Blender 2.92 and is now expanded upon in the alpha releases. The whole effect is a reusable modifier with easily tweakable settings. Replacing the instanced objects, adjusting their position offset and random rotation etc. allows for infinite variations.

Blend file is up on my Gumroad Store. Tutorial video is embedded down below. Have fun playing around and creating something mesmerizing.
