A Unity project from 2018 that put the five Platonic solids into mixed reality on Android so you could walk around them, which is a better way to understand why a dodecahedron has twenty vertices than a diagram is.
It is here for one reason: the palette. The five colours this site uses to encode its disciplines are the ones I assigned to the five solids in this project, and the solid-per-discipline idea is the same idea. Eight years of work later, the filing system I use to describe what I do came out of a student project about geometry.
