  1. 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.

  2. 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.

  3. 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.

  7. 3⃣ Pure CSS morphing polyhedra: dodecahedron → rhombicosidodecahedron → snub dodecahedron → rhombicosidodecahedron → icosahedron codepen.io/thebabydino/pen/gOj

    Positions & makes faces morph using CSS transforms. Which depend on CSS vars to keep code compact css-tricks.com/logical-operati
