I added the Rubik's
Cube,
a VT Octahedron,
and a shallow cut FT
Icosahedron(links
are to screenshots). I also have filled drawing working, thanks to
a great OpenGL techniqueI
found which drastically simplifies rendering concave polygons. The
approach requires no special mesh generation, which I incorrectly had
expected would be necessary.

Panning around with the filled drawing is a lot of fun - the ability to
orient puzzles arbitrarily is a big experience jump in the spherical world
just like it was for hyperbolic tilings. I find it especially neat when a
new sticker gets projected out to infinity and the background color
changes.

I also want to say congrats Eduard on your 24-cell solve. That is awesome
and inspiring! It's really cool to see a third solve, and it gives me hope
to maybe solve it someday myself :)

Cheers,
Roice
