Quiet Particle Field — effect skill for backdrops

For AI agents: find the right skill in one call — curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>" returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the how-to page.

Out-of-focus dots drift slowly in depth behind the content, adding life without motion noise.

What it does

Built on Ambient by tsparticles, MIT. The write-up and recipes below are varg's.

Sparse soft circles of two or three sizes, low opacity, drifting upward or sideways; a faint glow line optional.

When: Long holds on titles or quotes; calm sections of a film.

Watch out: Do not increase density until it looks like snow; 20–60 particles on 1080p is plenty.

Timing: Drift 5–20 px/s with a fixed seed so renders match.

Also called: bokeh particles, ambient dots, sparkles

In HyperFrames

npx hyperframes add starfield

Seek-safe: particle positions are a function of time and seed.

In Remotion

const rnd = (i:number)=> (Math.sin(i*999)*10000)%1;
Array.from({length:40}).map((_,i)=> <div style={{left:`${Math.abs(rnd(i))*100}%`, top:`${(Math.abs(rnd(i+7))*100 - frame*0.05*(1+i%3))%100+100}%`}}/>)

In CapCut

Media → Library: search "bokeh"/"particles"; Blend → Screen at 30–50% opacity over the background.
