Stained-glass window motion video

LEADLIGHT is an AI Skill for Claude Code, Codex and Cursor that renders a stained-glass window style motion video with an original score synthesised in code. A story told in a stained-glass window seen from a dark stone hall: cobalt and ruby glass in lead cames, brown grisaille detail, panes that glow only where a moving band of sunlight touches them, figures stepping at 8 fps while light and camera move on every frame, and captions on a parchment banderole, rendered as an MP4, a poster and a contact sheet.

- 10 original recipes: light-band clock, re-leading reveal, medallion panes, coloured sill patches and more

## FAQ

### How do I use this Skill?

Paste it into Claude Code, Codex or Cursor and give it the one message and the brand name. The AI installs GSAP and the render tools, writes a storyboard and renders the MP4, a poster and a contact sheet frame by frame in your project folder. [How Skills work](https://sketchry.app/blog/what-is-a-skill/#use)

### Why do only some panes glow?

A band of sunlight moves across the window and only the panes it touches light up; the rest go dim but never black. Figures step at 8 fps while the light and the camera move on every frame, and captions sit on a parchment banderole.

### Can the fonts be used commercially?

Yes. The Skill only uses open fonts licensed for commercial use (Noto Sans TC, Inter and others under the SIL Open Font License). Check the license before switching fonts.

### Does Sketchry receive my content?

No. The Skill runs inside your own AI tool, and the video is rendered on your own machine.

### How much does it cost?

All 81 Skills, future releases included: US$6 a month, US$29 for six months or US$99 once for Lifetime. Prices include tax.
