canvas-sketch + TypeScript

After installing canvas-sketch globally, create a new folder to hold your sketch:

mkdir my-sketch
cd my-sketch

Now run the following to generate a new default .ts file, package.json, etc:

function sqr (x) {
  return x * x;

function dist2 (v, w) {
  return sqr(v[0] - w[0]) + sqr(v[1] - w[1]);

Rendering High-Resolution Meridian Outputs

Meridian is a generative art project deployed on Ethereum, and distributed as unique, artist-signed tokens. This creates an interesting scenario where the value and acquisition of the art project is not tied to the scarcity of access to its media (such as high-resolution PNGs and fine art prints of the algorithm's output). And so, I've created some tools to help all audiences—whether collectors of the tokens or not—export high-resolution outputs of a given Meridian for personal and non-commercial means. For example: fine art printing to hang a Meridian on your walls, or using it as a social media avatar or banner, or including it in a blog post.

First, open the following page and scroll to the interactive component, showing the Meridian software: https://meridian.mattdesl.com/

In that page, open your DevTools Console in the browser, in Chrome it is under View > Developer > JavaScript Console. Each time you click the artwork, it
