Any idea how this kind of “generative art” could be achieved in AE without code?

Sometimes writing code is necessary to achieve a very specific procedural effect, but there’s a lot you could do with plugin like Trapcode Form and layer maps without ever writing a single line.

Trapcode Particular could be useful. It depends on the details of the movement.

An old post, it may be relevant …
