Particle starting points are placed using phyllotaxis (golden angle spiral arrangement), then a flow field function determines the direction each particle moves at every step. The piece demonstrates several field types (vortex, spiral, outward, inward, wavy, diagonal, interference, ripple) and shows how tweaking parameters like n (particle count), n_steps (journey length), and step_size (stride) changes the resulting visual texture, all while keeping the walker logic unchanged. ## Full article daily.dev links to this article rather than hosting it.
