Rainbow-colored trails spiralling out of the centre and curling back, like a swaying sea anemone on black

- **Install:** `pnpm add @tsparticles/engine @tsparticles/slim @tsparticles/preset-<name>`
- **Registry:** tsparticles · **Framework:** html · **License:** MIT

## Prompt that renders it frame-exact

Use the tsParticles Sea Anemone preset (https://particles.js.org/demos/recipes/sea-anemone, MIT, options in github.com/tsparticles/presets/blob/main/presets/seaAnemone/src/options.ts) as a hypnotic full-frame background for a music, art or intro sequence, with type kept to the edges. Load @tsparticles/engine and @tsparticles/preset-sea-anemone (or its CDN bundle tsparticles.preset.seaAnemone.bundle.min.js), call loadSeaAnemonePreset(tsParticles), then tsParticles.load({ id, options: { preset: "seaAnemone", fullScreen: { enable: false } } }) into a full-frame div. Pre-roll a second or two so the tentacles have grown before the scene starts. tsParticles ticks on requestAnimationFrame and derives each step from the frame timestamp, so make it deterministic: seed Math.random before loading, swap requestAnimationFrame for a queue you flush once per video frame with the timestamp frame × 1000 / fps (keep fpsLimit at or above the video fps), and render frames in order from the moment it starts (it is a running simulation, so replay from that point after a backwards seek). Narrow the color animation to brand hues instead of the full rainbow, lengthen the trail for smoother curves, and lower particles.number.limit (300) for a sparser bloom.
