# Sand Dune Hero

> A sea of dunes at golden hour beside your headline. Sharp crests with long shadows run to a hazy horizon under a low sun, wind ripples travel across the slopes, sand streams off the crests in thin plumes, and grains glint as the light catches them, while the camera drifts slowly on a closed loop. The dunes are ray-marched in a hand-written shader, so the light, shadows and haze are worked out per pixel. Your agent sets the sand, shade, sky and sun colors, fonts, logo, headline and buttons, checks contrast at four widths and records a seamless 1080p loop.

- Output: Web, Animated WebGL hero · page + embed + 1080p video
- Price: $6.90 one-time, or included in Pro
- Page: https://lookbk.dev/skills/sand-dune-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`).
- At runtime, nothing but WebGL: the shader is inlined in the page. Fonts load from jsDelivr (the pinned list) or Google Fonts; without the network the page uses system fonts. Without WebGL visitors see the still.

## Install

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