Glyph Matrix

GlyphMatrix is a client-side animated canvas that renders a grid of randomly changing glyphs. It supports configurable glyphs, mutation timing, fade behavior, cell sizing, and CSS color values for light or dark themes.

Installation

pnpm dlx shadcn@latest add @magicui/glyph-matrix

Requires @magicui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { GlyphMatrix } from "@/components/ui/glyph-matrix"export function Example() {  return <GlyphMatrix className="absolute inset-0" />}
  • Add atmospheric motion to hero sections, landing pages, dashboards, or empty states.
  • Use as a decorative background behind readable foreground content.
  • Create subtle developer, terminal, sci-fi, or data-visualization aesthetics.
  • Pass a theme-aware CSS color when the surrounding light or dark theme changes.

Examples

Hero background

A decorative matrix effect positioned behind hero content.

hero-background.tsx
import { GlyphMatrix } from "@/components/ui/glyph-matrix"export function HeroBackground() {  return (    <section className="relative min-h-[420px] overflow-hidden">      <GlyphMatrix className="absolute inset-0" color="#64748B" fadeBottom={0.8} />      <div className="relative z-10 flex min-h-[420px] items-center justify-center">        <h1 className="text-4xl font-bold">Build faster with modern tools</h1>      </div>    </section>  )}

Theme-aware color

Uses a CSS custom property so the canvas color follows the active theme.

theme-aware-color.tsx
import { GlyphMatrix } from "@/components/ui/glyph-matrix"export function ThemeAwareMatrix() {  return (    <div className="relative h-64 overflow-hidden rounded-xl bg-background">      <GlyphMatrix color="hsl(var(--muted-foreground))" className="absolute inset-0" />    </div>  )}

Dense custom glyph grid

Configures smaller cells, a custom glyph set, and faster mutation timing.

dense-custom-glyph-grid.tsx
import { GlyphMatrix } from "@/components/ui/glyph-matrix"export function DenseMatrix() {  return (    <GlyphMatrix      className="h-80 w-full rounded-lg bg-slate-950"      glyphs="01ABCDEF"      cellSize={11}      mutationRate={0.08}      interval={60}      fadeBottom={0.35}      color="#22C55E"    />  )}

Subtle decorative texture

Uses a low mutation rate and no bottom fade for a consistent background texture.

subtle-decorative-texture.tsx
import { GlyphMatrix } from "@/components/ui/glyph-matrix"export function SubtleTexture() {  return (    <GlyphMatrix      className="h-48 w-full rounded-md border"      cellSize={18}      mutationRate={0.01}      interval={140}      fadeBottom={0}      color="rgb(148 163 184 / 0.8)"    />  )}

API reference

PropTypeDefaultDescription
glyphsstring"01·•+*/\\<>="Characters to randomly pick from when initializing and mutating cells.
cellSizenumber14Cell size in pixels; the same value is used as the glyph font size basis.
mutationRatenumber0.04Approximate proportion of cells selected for mutation on each tick. The implementation always mutates at least one cell.
intervalnumber90Animation tick interval in milliseconds.
fadeBottomnumber0.6Controls the fade toward the bottom of the canvas. Set to 0 to disable the fade.
colorstring"#6B7280"Glyph color as any CSS color string, including hex, rgb(), hsl(), and oklch() values. The value is resolved to RGBA for canvas rendering.
classNamestringnullInherited from React.HTMLAttributes<HTMLCanvasElement>. Merged with the built-in pointer-events-none class.
styleReact.CSSPropertiesnullInherited inline canvas styles. The component supplies width: 100%, height: 100%, and display: block; provided style values are spread afterward and can override them.
HTML canvas attributesReact.HTMLAttributes<HTMLCanvasElement>nullAll other standard React HTML attributes accepted by a canvas element are forwarded to the rendered canvas, including id, title, data attributes, and event handlers.

Accessibility

  • The rendered canvas is marked aria-hidden="true" by default because the animation is decorative and contains no semantic content.
  • Do not use the component as the sole way to communicate information, status, or controls; provide equivalent accessible text or UI separately.
  • The component adds pointer-events-none by default so the decorative canvas does not obstruct interaction with content beneath it.
  • If supplying an aria-hidden value through forwarded props, remember that the spread props are applied after the component's default aria-hidden attribute and can override it.
