Dither cloud
Soft drifting clouds drawn in ordered-dither pixels, violet to pale lilac as they thicken, that glow up under the pointer and ripple outward on click.

Background Studio: tune it below, then copy the code
Your system asks for reduced motion: the demo shows its final state and nothing moves.

Dither cloud example
Code
It follows the controls above: change an option and the code changes with it.
<script src="https://search.axi0.io/axi0/motion/motion.js" defer></script>
<axi0-dither-cloud cover></axi0-dither-cloud>import { DitherCloud } from "./motion/react/DitherCloud";
<DitherCloud /><script setup lang="ts">
import DitherCloud from "./motion/vue/DitherCloud.vue";
</script>
<template>
<DitherCloud />
</template>const fx = document.createElement("axi0-dither-cloud");
document.querySelector("#hero").append(fx);The wrappers: DitherCloud.tsx (React, TypeScript) and DitherCloud.vue (Vue). Both render the same attributes as the HTML; the loader does the rest.
Options
| Attribute | Default | What it does |
|---|---|---|
pixel | 3 | Pixel size |
shape | square | Pixel shape |
scale | 1 | Cloud size |
colors | auto | Colors, comma separated (empty: the palette for the page's theme) |
background | auto | Background color (empty: the theme's) |
speed | 1 | How fast it moves |
theme | auto | Light or dark palette (auto: from the page behind it) |
cover | false | Fill the nearest positioned parent, behind its content |
Accessibility
Decorative: the canvas is aria-hidden and takes no focus; with cover it ignores the pointer, so the content above it stays clickable and readable. With no pointer the glow wanders on its own, so touch and keyboard users see the same scene; a tap ripples like a click. Drawn by the shared WebGL runner below device resolution (never more than one pixel per CSS pixel, device pixel ratio capped at 2); it starts when it comes within 300 px of the screen, the frame loop stops off screen and in hidden tabs, and reduced motion draws one still frame with no movement. Without WebGL it shows a still gradient in its own colors.
Size
dither-cloud.js is 0.8 KB gzip, with gl.js 2.1 KB and backgrounds-kit.js 3.4 KB it needs. A page loads the loader (2.9 KB) and core.js (1.4 KB) once, whatever it uses.
