html

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

<ascii-art piece="orchid" 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="orchid" mono>, for one ink.

react

// npm install ascii.rest
import { Ascii } from "ascii.rest/react";
import { orchid } from "ascii.rest/pieces";

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

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

astro

---
// npm install ascii.rest
import Ascii from "ascii.rest/astro";
---

<Ascii piece="orchid" 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

// npm install ascii.rest
import { mount } from "ascii.rest";
import { orchid } from "ascii.rest/pieces";

const el = document.querySelector<HTMLCanvasElement>("canvas")!;
const stop = mount(el, orchid, {"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 orchid

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("orchid", { seconds: 2 }) from ascii.rest/terminal shows it as a splash screen.

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

/*
 * orchid: the Orchid logo, a flower of five petals, with a glint crossing it
 * every few seconds.
 *
 * Drawn from Orchid's own symbol, from orchid.ai/brand: 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 in its ink, and in its light version on
 * a dark page, where the ink 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.
