# Deep Jellyfish Hero

> A dark, cinematic website hero on five seconds of generated footage: a translucent moon jellyfish glowing cyan and violet in a black deep-sea void, pulsing twice and rising slowly while glowing plankton twinkle around it. A giant serif word sits behind the jellyfish, which is cut out of every frame and drawn over it, under an italic line that fades in word by word. Around it, liquid-glass panels: a floating bar with your links, a kicker chip, a glass second button, number cards (one can count up) and a scene card whose line fills as the film plays. Your agent writes one hero.json with your words and links; the build checks every length and writes a page and an embed, and a recorder makes a 1080p MP4 with sound. It suits a sleep, wellness, meditation, science, biotech, music or any calm, glowing, nocturnal brand.

- Output: Web, Cinematic hero on generated footage · liquid-glass UI · words behind the subject · page + embed · 1080p MP4 with sound
- Price: $4.99 one-time, or included in Pro
- Page: https://lookbk.dev/skills/deep-jellyfish-hero

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge, for the checks and the video (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`).
- A web server for the page. Opened straight from disk (`file://`) browsers won't let the page draw the film, and it shows the still; `node scripts/serve.mjs out` serves it on localhost.
- Internet access when the page is opened: GSAP and the fonts load from jsDelivr (pinned, with an integrity hash) and Google Fonts. Without GSAP the hero shows its still with every word in place.

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add deep-jellyfish-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/deep-jellyfish-hero` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/deep-jellyfish-hero`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/deep-jellyfish-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.
