Small particles drift across the screen and follow currents and eddies stirred by the pointer. Like dust in a sunbeam revealing air movement, their paths make an invisible flow visible.
`count` sets the number of particles (default 6000, range 1000–16000), `size` sets their size (default 1.2, range 0.3–3), and `speed` sets how quickly they follow the flow (default 1, range 0.2–3). `force` controls how strongly the pointer stirs the field (default 1, range 0–3); `momentum` controls how long it continues after the pointer lifts (default 0.6, range 0–1).
This generator fills the screen without an input image. A plain background makes the paths readable; many particles or long trails can crowd the scene, so avoid placing them behind text.
When to use
Use it for a flow-focused hero background, pointer-responsive decoration, or drifting dust. Avoid it on text-heavy screens or where a crisp shape needs to remain the focus.
