What you get

  • A one-page hero and a paste-in embed with your name, words, numbers and links
  • The jellyfish cut out of every frame and drawn over the giant serif word
  • Liquid-glass bar, chip, button and cards in Fraunces and Inter, with an intro tied to the film's own clock
  • A phone layout: the headline stays in the frame, the introduction and buttons move into a block underneath
  • Stills of the last frame for reduced motion, no WebGL, blocked autoplay or a slow connection, so it is never blank
  • A 1080p MP4 with the film's sound and a poster, rendered frame by frame
  • Checks at 390, 768, 1280 and 1920 px for overflow, overlaps, links and script errors
  • Open-source licenses for every part it builds on

Good fit

  • Sleep, wellness, meditation, science and biotech brands can open on a glowing moon jellyfish pulsing slowly upward through a black deep sea.
  • Night-time brands get a cyan glow on near-black, a soft Fraunces headline and a jellyfish whose tentacles drift over the end of the big word.
  • Apps and labs can show hours of audio, depths or study counts in glass cards, with a scene card that names a track and its length.

Not for

  • Swapping in your own video: the matte is made for this film, and the scene (jellyfish) is the design
  • Changing the colors, fonts or layout through settings (every word, number and link is yours; the look is fixed)
  • Long headlines: the big word takes up to 8 characters and each field has a limit the build enforces
  • Sound on the live page (browsers only autoplay muted video; the MP4 keeps the sound)
  • Full landing pages below the hero (see the Landing Pages series)

About this skill

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.

Example request

Make a Deep Jellyfish hero for our biotech startup: italic line 'Life, made', big word 'Visible', our links and buttons, and record the video.

FAQ

Can I put my own video behind the headline?

No. The matte that cuts the jellyfish out was made for this film, so the footage is part of the design. Every word, number and link is yours through hero.json; the footage, colors, fonts and layout stay as they are.

How long can the words be?

The italic line takes up to 18 characters, the big word behind the subject up to 8 and the wordmark up to 14. The build lists every field that is too long and writes nothing until they are fixed, and the check fails if anything spills or overlaps.

Is the jellyfish see-through over the words?

A little, like a real one. The bell is solid in the cut-out, and the thin tentacles let some of the word show through, which reads as depth rather than a mistake.

Which agents is Deep Jellyfish Hero written for?

Any agent that reads SKILL.md folders, including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

Do I own what I make with it?

Yes. Everything your agent makes with this skill is yours, including for client and commercial work.

What if it doesn’t work for me?

Email support@lookbk.dev within 7 days of buying and we’ll fix it or refund you.
