I have been following Anders Hoff [1][2]. He does some cool stuff with plotters.
I made an egg plotter back in the early 2000s based on The Art of Motion Control site [3], and then I went off to build CNC tables and do wood carvings in 3-axis, and then 4, and 5-axis machining. I am really interested in the community around making ceramic 3D printers where they mix their own clay. All creative and really cool stuff!
You can turn 3D scenes into 2D vectors.
