Where do I paste this prompt?

Into any assistant that writes code: Claude, ChatGPT, Cursor, Lovable or Claude Code. Ask for a single index.html file, save it and open it in the browser. It uses three.js 0.160 (fragment shader, raymarching).

Can I use it on my website?

Yes. The prompt is free and the code your assistant writes is yours. If you’d rather have the finished version, with your photos and words and ready to publish, there’s the related kit.

Is the video what really comes out?

Yes. It’s the page the prompt made, filmed without touching the code by hand; the prompt was rewritten 1 time, and this is the last one. Every assistant writes different code, so yours may vary a little.

Prompt of the day · 24 October 2026

A liquid blob that melts toward your cursor

What the prompt makes, filmed as it came out

Five pastel chrome balls orbit, breathe and merge into one liquid shape under a big headline. The cursor (or a finger) pulls the nearest one, so the blob stretches and splits toward your hand.

Make one index.html with three.js (import map, three@0.160 from unpkg). Full-screen fragment shader on one plane, background a soft cream-to-lilac gradient. A raymarched liquid blob: five metaballs merged with a smooth minimum (k 0.5) that orbit slowly and breathe. Size it from the screen width: the whole blob always stays inside 80% of the width and ~55% of the height, centered a bit low, fully in view on a phone. Shade it like pastel soap-bubble chrome: Fresnel rim, a soft cosine palette (blush pink, sky cyan, pale gold, no green), bright specular, high ambient so nothing turns dark. The cursor (or a finger) pulls the nearest ball toward it with easing, so the blob stretches and melts toward your hand. At the top, above the blob, the headline "Make it liquid" in a huge bold sans (about 12vw), #1a1a2e. 64 march steps max, pixel ratio min(1.5, devicePixelRatio). 60 fps on a phone.

What it’s for

The hero of a studio, brand or product launch: one calm, playful object under the headline.
A landing page for an app or a drink, where “liquid” or “soft” is part of the brand.
A 404 or coming-soon page that people play with instead of leaving.

Variants to try

Add the line at the end of the prompt. We haven’t filmed these: try them yourself.

Your brand coloursUse a palette of #2f5bff, #8fd3ff and #ffffff instead of pink, cyan and gold.
Dark versionBackground a #0d0d14 to #1c1430 gradient, headline #f5f2ff, and keep the high ambient so the blob never turns black.
More dropsUse eight metaballs instead of five, slightly smaller.
