Pointer Swarm

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/pointer-swarm.tsx.

Install the pastetaste component "Pointer Swarm" (pointer-swarm) into this Next.js project and use it.

What it is: A field of spring-tethered particles that the pointer pushes, pulls or stirs; displaced dots light up and streak. One 2D canvas.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/pointer-swarm.json
   (it writes components/pastetaste/pointer-swarm.tsx; install any npm packages it reports).
2. Import it: import { PointerSwarm } from "@/components/pastetaste/pointer-swarm" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- color: string = computed CSS color — Resting dot colour; inherits `color`.
- accent: string = '#c8ff3b' — Colour of displaced dots.
- mode: 'repel' | 'attract' | 'swirl' = 'repel' — What the pointer does to nearby particles.
- spacing: number = 24 — Distance between home positions in px; smaller means more particles (capped at ~2600).
- radius: number = 170 — Radius of the pointer influence in px.
- strength: number = 1 — Force multiplier.
- size: number = 1.4 — Dot radius in px at rest.
- roam: boolean = true — A ghost pointer wanders through the field while the real one is idle.
- opacity: number = 0.55 — Resting opacity of the field.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
