Tried out some Lego sphere possibilities - here is one I quite like, could be classified as a cuboctahedron I suppose. Made from these triangular pieces joined by hinges in the corners.

The triangles are apparently known as "Plate, Modified 6 x 6 Hexagonal with Pin Hole" on Bricklink, the second hand Lego store. Pretty hard to find unless you order them from there

I signed up to some pottery sessions as a birthday present to myself. One of the projects I worked on was an icosahedron teapot!

Luca Pacioli’s (c.1445–1517) book ‘Divina proportione’ (written 1496–8, published 1509) is famous in the history of mathematical beauty, but mostly for the wrong reasons.

The term ‘divine proportion’ refers to Euclid's ‘extreme and mean ratio’, known since the late 18th century as the ‘golden ratio’: $1.61803\ldots:1$.

Pacioli's use of the term ‘divine’ **was not based upon aesthetic appreciation**.

Rather, he made a mystical identification of certain properties of the ratio with attributes of God. E.g., the incommensurability of the ratio = the indefinability and ineffability of God.

But Pacioli aesthetically admired the five regular polyhedra — the platonic solids — and the archimedean solids that he knew. In the dedication of ‘Divina proportione’ he wrote that hoped that his patron would see ‘their most sweet harmony’. He linked the aesthetic value of the solids to that of the sphere, from which he saw them as deriving. He seems to have placed special value on the ‘most noble’ dodecahedron.

In his portrait (attached), a dodecahedron sits on top of one of his books as a symbol of mathematical success. His diagram is part of the construction of the tetrahedron. A glass rhombicuboctahedron hangs behind him.

I find it fascinating how #ChristmasTrees have become much more #abstract in #London this year.
Fewer trees (fake or real) Instead, an array of semi-plantonic cones, shining with light. More likely made of #baubles than having them hanging.
What will #Christmas evolve into next?

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

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.

Do you like making things out of paper?

I have an activity pack for you:
https://britthub.co.uk/shop/platonic-solids-paper-shapes-activity-pack/

I send you flat shapes, made from colourful card, plus instructions for folding and sticking. You fold and stick.

Joy is experienced at having made a thing. Maths and art, together as they should be.

Apollonian gaskets based on Platonic solids. The vertices of a tetrahedron/octahedron/icosahedron are used for the centre positions of the initial circles. These are Riemann-sphere-mapped to the complex plane, where the gasket is iterated for more circles, and the result is mapped back onto the sphere. It's a little roundabout, but it works for me, and the heaviest part by far is drawing the visuals.
