# Paper Marbling Hero

> A hero section that marbles a sheet of paper beside your headline. Drops of your inks land on the bath and spread into rings that push each other aside. Then a comb is drawn through, its pins visible as it travels, pulling the rings into chevron, nonpareil, wave or bouquet patterns with fine dark veins. A strip of paper skims the bath clean and the next seed starts a new sheet. A row of named ink swatches lights up as each ink drops. Your agent sets your inks, fonts, logo and words, checks contrast at four widths and records a frame-exact 1080p video.

- Output: Web, Animated WebGL hero · page + embed + 1080p video
- Price: $6.90 one-time, or included in Pro
- Page: https://lookbk.dev/skills/paper-marbling-hero

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge, for the checks and the recording (the scripts find it; set `CHROME_PATH` if they don't).
- ffmpeg, for the video (`brew install ffmpeg`, `winget install ffmpeg`, `apt install ffmpeg`; or set `FFMPEG_PATH`).
- Nothing else at runtime: the effect is plain WebGL inlined in the page. Only the fonts load from a CDN; without the network the page uses system fonts. Without WebGL, visitors see the SVG still of the same sheet.

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add paper-marbling-hero
```

The first run prints a sign-in link; open it, approve, and run the command again. Pro skills install for accounts that bought them or have Pro.

Where it installs:

- Run by Claude Code: `~/.claude/skills/paper-marbling-hero` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/paper-marbling-hero`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/paper-marbling-hero` when `~/.claude` exists.

Add `--claude` or `--shared` to write only one of those folders, or `--project` to install into the current folder instead. Start a new agent session afterwards so it picks up the skill.
