Curious to know what pen plotter was used here… didn’t look like article mentioned it.

I’m a big fan of Dan Catt and his work with generative art and pen plotting.

The author mentioned that the maker of their pen plotter is evil mad scientist, so it's likely they're using the AxiDraw

That is correct. I use AxiDraw SE/A3 and I love it. One of the best purchases I ever made.
