I want to do some laser etching with this format, though the density or ultimately path length might take more time than I want.

This is amazing

It evokes the feeling of nothingness

All of the shapes are “empty”, in the sense that there is no real closed-loop outer edge that contains them

But I perceive them as sort of self-contained objects

Thank you for sharing this, very cool

I love space filling curves. Literally takes a dimension-1 object that can create any object of finite dimensions. All perimeter no area/volume.

The algorithm behind this has to be super fun

Is this a fast TSP solver?

I read the tech blog. It's basically a TSP solver optimizing for the longest path. Generate points based on alpha channel, generate a maximally connected planar graph derived from nodes in step 1, use DFS to draw an arbitrary path, then invert triangular inequality to make the path gradually longer. There are some special case considerations like disjoint graphs.
