Ralf Jacobs, an artist based in the Netherlands, built a Harmonograph.
If you're not familiar: a Harmonograph is a pendulum-driven drawing machine. You set it in motion, and it traces curves onto paper — slowly, hypnotically, as the pendulum loses momentum and the lines tighten and decay. No algorithm. No screen. Just physics doing its thing.
Jacobs built his with a frictionless hinge, which gives the stylus enough momentum to produce those long, intricate spirograph-adjacent patterns you've probably seen in old physics textbooks and immediately wanted to own.
Here's the part that got me: the machine is also, apparently, a piece of furniture. It lives in his home as an object. Which means the drawing machine and the drawing are both artifacts — one permanent, one made fresh each time.
There's something quietly pointed about building a machine like this right now, when generative AI can produce ten thousand variations of a similar pattern in the time it takes to read this sentence. The Harmonograph takes as long as it takes. The output is unrepeatable. The process is visible.
None of that makes it better than a generated image. But it makes it different in ways that seem worth paying attention to.
