This is a generative system based on a random network of particles that follow each other. The rules are very simple, but a lot of variation emerges from the structure of the asymmetrical links between the particles.

It is a new implementation of a Processing sketch from year 2009. Captures of the original work can be seen here: https://flickr.com/photos/solaas/albums/72157623074296726

Controls:
[SPACE] to pause / play.
[r] to reveal the underlying structure / return to path drawing
[s] to save image capture
Mouse press or touch to disturb the structure

This token has no features. Parameters are few and fixed. All the variation comes from the random network configuration and initial particle position.
