<DitherEffect effect="plasma" />

The classic demo-scene plasma: four sine fields summed and smoothed through the palette. scale controls the density of the pattern.

The props group like this:

Texture: scale.

Double the scale for a denser, cellular pattern.

<DitherEffect effect={"plasma"} params={{"scale":4}} palette={["#0b0014","#4a0d77","#c72a92","#ff8c4a","#ffe6a8"]} cell={2} matrix={8} speed={1} />

A two-colour palette snaps the plasma into a duotone print.
