I have yet to crack the math, I’ve been banging my head against the wall with various implementations but this is a lot worse than the Gondola’s double polar system. I’d like the laser to be able to project a cartesian system in any position relative to the surface it’s drawing on. Alas, I’ve only been able to get decent results in ideal positions.

This one is very abstract except when viewed from a good distance it comes together.
Runestone of Memory
I often contact artists to see if they’d like to do something public on the big plotter, and I’m often met with silence :). Sometimes though, I meet the rare characters who are completely fine doing something cool just because it’s cool, new, and takes their art in another dimension, oh and by the way there’s $0 to be made for either of us. I appreciate disinterested people, and Irish artist Patrick Boullier is such a person. He kindly provided a high resolution scan of his amazing piece: Runestone of Memory so I could try to turn that into penstrokes for the giant plotter. After several trials and help from Vectorizer.ai (top of the line for SVG tracing), I got somewhere we both felt was good, and so it ran on the big plotter for a week.
As is routine, the public reveal was preceded by several smaller scale trials.
This is an awesome piece on Norse mythology riddled with symbolism. I highly recommend reading the explanation of some of it (scroll down some).
