Very nice resource, pen plotters are so fun. One of my favorite subreddits is /r/plotterart - feels like one of the last few hobby-related subreddits I can go to that retained the feeling of early days subreddits, just people showing cool stuff they've made.
More of this please.
The plotter shown reminded me of the lowly harmonograph [1]. As old or older than Scientific American.
Awesome!
I've rigged my 3D printer to use as a 2D plotter, and had a ton of fun programming it to draw fractals like the Dragon Curve [1].
I also made a tool to do cursive handwriting/calligraphy with it, to make fancy postcards and whatnot [2].
Guess this would fit right on that blog :D
