What is Tinkersynth?

Updated

Tinkersynth is a browser-based experimental art project by Josh Comeau, described on the site as a place to "create unique designs by manipulating whimsical machines and making serendipitous discoveries." In practice, that means you don't draw anything directly — you adjust the controls of a small machine and watch a generative design take shape. It's aimed at people who want to play with generative art rather than produce a precise, predetermined image.

How it works

The core loop is manipulation and observation:

  1. You open a machine (each one is a different generative "toy").
  2. You change its controls — sliders, toggles, and similar inputs.
  3. The design on the canvas updates in response.
  4. You keep adjusting until something interesting appears, then save or export it.

The site frames this as "serendipitous discovery," which is the honest description: you're exploring a parameter space, not following a recipe to a known result. Two people starting from the same defaults will usually end up somewhere different.

What you can expect

  • Generative output, not freehand drawing. Your creative input is through the machine's parameters, not a brush.
  • Multiple machines. The project is built around more than one whimsical machine, each producing a distinct style of design.
  • An experimental art project, not a productivity tool. It's made for exploration and play, and the site presents it that way.
  • Browser-based. There's nothing to install; you use it on the web.

Who it's for

If you want to… Tinkersynth fits?
Explore generative art with no setup Yes — it's built for exactly this
Get a specific, predictable image Not really — output depends on your exploration
Learn how parameter-driven design works Yes — the controls make the mechanism visible
Use it as a professional design tool Unclear from the site; it's presented as an art project

Practical notes

  • The site is maintained by Josh Comeau, with a copyright notice reading "© 2019-present."
  • A FAQ and a Privacy Policy are linked from the page.
  • The site's own description is the most reliable statement of intent: experimental, whimsical, discovery-oriented.

If you're curious what generative art feels like when the machine does the drawing and you do the steering, Tinkersynth is a low-commitment way to find out — open a machine, move a control, and see what happens.
