I love it. I've been thinking of generative art in the physical world somewhat along these lines for a while now but haven't actually gotten around to the "physical world" part of these dreams yet. Mostly just been having fun coming up with interesting generative stuff in Processing. Your system seems really well designed, and that UI is pretty great. I'm jealous both of the well-designed system you made, and that you can use it to make things (I have many bare walls I intend to one day fill with generative art I've made).
Plotters fit so well with generative art. I highly recommend considering purchasing one! In fact, I learned about them on HN in 2018, and now using them to make art is my full time job.
