  1. And here's a skeletal octahedron transforming into three cuboids (and back again).

    Even though this seems easier to visualise, I find some of the configurations fascinating, especially the three cuboids when three edges meet at common points, and the three cubes.

  6. Icosahedron with perfect Islamic geometric symmetry. Trying to make use of colours that make the work pop instead of resorting to black/white or wood-based colours.

  9. Playing around with an office magnet toy and made a shape I think is fun. It's right pentagonal prism with two of the prism edges removed. So we end up with a shape that's got two pentagons, one rectangle, and a two skew hexagons. (Or, the pentagons can be skew too, or the two hexagons can be plane I think though that is not actually feasible with the magnet toy.)

    Its Euler characteristic is 10 - 13 + 5 = 2, just like a real polyhedron. :)

  10. A render I made today with all the Johnson solids and some related shapes:

    I'm trying to improve that Wikipedia page some more.

  11. The thirteen archimedean solids are the polyhedra (other than the five regular solids) all the faces of which are regular polygons and where for each pair of vertices some symmetry transformation carries one vertex to the other (see 1st attached image).

    According to Pappus (fl. c.300–c.350 CE), who wrote a half-millennium later, Archimedes discovered them. The context of Pappus' report suggests that Archimedes was seeking polyhedra inscribable in spheres.

    Archimedes excluded the infinite classes of prisms and anti-prisms, in which two n-gons are joined by squares or equilateral triangles (2nd attached image). Although they satisfy the definition, and are technically inscribable in spheres, they are somehow not ‘sphere-like’.

    This suggests that Archimedes may have been influenced by the aesthetic preference for circles and spheres that descended from Pythagoras.

  15. One of my earliest #CSS #3D demos on @codepen: how to (de)construct a dodecahedron codepen.io/thebabydino/pen/ALQ

    A dodecahedron is one of the 5 regular polyhedra = made up of only identical regular polygon faces. Regular polygons have all edge lengths and vertex angles equal.

  19. Given that I am still re-reading the first page of this book for like the tenth time, I have doubts about “we can simply say”
