Yours? The readme snippet puts it in your README, moving, in GitHub's light and dark themes. A post with the video or GIF from the downloads moves too; a link alone shows its card, which holds still.

html

<script type="module" src="https://ascii.navinhill.com/ascii.js"></script>

<ascii-art piece="vercel" options='{"shine":5}'></ascii-art>

No install and no build step. ascii.js defines the <ascii-art> tag, loads the piece from ascii.rest, plays it while it is on screen, and holds the first frame for anyone who prefers reduced motion. Add mono, <ascii-art piece="vercel" mono>, for one ink.

react

// git clone https://github.com/jamesnavinhill/ascii
import { Ascii } from "ascii.rest/react";
import { vercel } from "ascii.rest/pieces";

<Ascii piece={vercel} options={{"shine":5}} />

A client component, so it works in the Next.js app router as it is. Pass the name instead, piece="vercel", to fetch the piece only when it mounts. Add mono for one ink.

astro

---
// git clone https://github.com/jamesnavinhill/ascii
import Ascii from "ascii.rest/astro";
---

<Ascii piece="vercel" options={{"shine":5}} />

Renders the first frame on the server, so the page is whole before any script runs, then plays the piece once it loads. Add mono for one ink.

typescript

// git clone https://github.com/jamesnavinhill/ascii
import { mount } from "ascii.rest";
import { vercel } from "ascii.rest/pieces";

const el = document.querySelector<HTMLCanvasElement>("canvas")!;
const stop = mount(el, vercel, {"shine":5});

mount plays a piece in a <pre>, or on a <canvas> for the coloured ones, and returns a function that stops it. Every piece, option and frame is typed. Mount it in a <pre> for one ink.

terminal

npx ascii.rest vercel

Plays it in your terminal, in colour, until you press a key. Add --mono for the terminal's own colour. Add --light for a light terminal. Add --seconds 5 to stop it on its own; npx ascii.rest list shows every piece. In a CLI of your own, play("vercel", { seconds: 2 }) from ascii.rest/terminal shows it as a splash screen.

vercel, as a light README shows it
light, vercel.svg
vercel, as a dark README shows it
dark, vercel.dark.svg

An animated SVG that needs no script, so it plays in a GitHub README, which runs none. GitHub shows the dark one in its dark theme. It holds still for anyone who prefers reduced motion.

vercel.ts

[js] [github] 
/*
 * vercel: the Vercel logo, a black triangle, with a glint crossing it every
 * few seconds.
 *
 * Drawn from Simple Icons' vercel.svg (CC0): each cell holds the character
 * whose shape best matches the logo's edge through it, and 8 where the logo is
 * solid. On a canvas it is black, and a light grey on a dark page, where black
 * would sink into it; in a <pre> it is one ink, from the same drawing. The
 * logo is a trademark of its owner, shown here to name the company.
