Tangent: I really like vornoi diagrams and part of me thinks there's a hidden, precious concept they represent. I didn't get their relation to the article but was wondering if they have applications in engineering/sciences.
A Voronoi diagram is created when you color every point on an image according to which discrete point it is closest to.
So in this case, I see the diagrams as representing the boundaries drawn when projecting / quantizing complex ideas into a set of central points that are insufficient for catching all of the nuance of the original. How well can you adapt a nuanced idea to a different space?
If Language A has an idea that exists at one point in space, which is the closest word in Language B that might be used to represent it? A Voronoi diagram is one possible way of illustrating it.
Tangent on your tangent: this GDC presentation from 2016 is probably my favorite real-world application of Voronoi Diagrams, and uses them for N-player split-screen camera control: https://www.youtube.com/watch?v=tu-Qe66AvtY&t=1594s
I have a lingering dream in the back of my mind to make a single-couch Liero-style casual game for N-players with good dynamic camera support using this technique.
