Maelstrom
A whirlpool of particles, wound into the drain
A whirlpool of points seen from the rim, its arms winding tighter as they near a funnel at the centre. The dots visibly circle the drain rather than bob on a waving floor, and froth rides the forward face of each arm and thickens toward the eye.
Rendering cost: heavy. A raymarch or escape-time loop per pixel: cap the pixel ratio, or keep it to a card rather than a fullscreen background. How to tune it
Tune Maelstrom free. Take it when you are ready.
The background itself, with your settings already saved in, ready to drop into your site — this one and the other 60. Paid once, no subscription, and every background added later is included. What you get.
