Light Shafts

BackgroundsCanvas

A fan of soft light beams from one edge on a 2D canvas, each breathing on its own phase. CSS blur, no WebGL, pauses off-screen.

Paste it into Claude Code: it installs the component, asks for your brand and content, and places it on the page you name.

Install

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

npx shadcn@latest add https://pastetaste.com/r/ray-fan.json

Prompt

Install the pastetaste component "Light Shafts" (ray-fan) into this Next.js project and use it.

What it is: A fan of soft light beams from one edge on a 2D canvas, each breathing on its own phase. CSS blur, no WebGL, pauses off-screen.

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/ray-fan.json
   (it writes components/pastetaste/ray-fan.tsx; install any npm packages it reports).
2. Import it: import { RayFan } from "@/components/pastetaste/ray-fan" (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):
- origin: 'top' | 'bottom' | 'left' | 'right' = 'top' — Edge the beams come from.
- color: string = var(--pt-shaft-color, #ffffff) — Beam colour, any CSS colour.
- count: number = 9 — Number of beams.
- spread: number = 70 — Fan angle in degrees.
- length: number = 1.1 — Beam length as a fraction of the canvas diagonal.
- intensity: number = 0.55 — Peak brightness, 0 to 1.
- speed: number = 1 — Animation speed; 0 freezes it.
- blur: number = 28 — Softness in px.
- className: string — Class name on the root element.
- style: CSSProperties — Inline styles merged over the defaults.

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