- The Great Dodecahedron is my favorite polyhedron, and it's possible to build one out of paper. Give it a try when you get a chance !

- That makes atleast two of us. Where I live, they festoon a few of these on Christmas in addition to the more traditional five pointed star. I have always wondered whether it had easy enough net.
The Icosahedron though, that makes my heart skip a beat sometimes.
- Related work-in-progress if you like polyhedra and tiling transformations: https://ixxyxr.github.io/polyhydra-web/
It has the Kepler-Poinsot polyhedra and allows you to apply a superset of Conway Operators to them. No true stellation currently (stellation isn't an edge-replacement operator so can't be mimicked by Conway-esque operations)
- Great article on stellated forms! I almost missed it due to the subtle unintuitive title!
- The fact that f(L^2) is positive can be seen without inspecting coordinates: after all it is the length of e_i', hence positive.
