Although the Roman #Dodecahedron was, of course, a fidget spinner, there is also a skill game that could be played with it, too.

You start by inserting a ball as big as the largest hole allows, and then spin the d’hedron in each axis without letting it fall out.

If you master that, you move on to the next smaller ball which can now potentially fall out of two holes. Third smaller ball = three holes. Difficulty increases.

Winner is whoever can keep the smallest ball going the longest.

My theory is that #Roman_Dodecahedrons are combination stands and hand-holders for the #Roman equivalent of Rushlights.

The multifaceted design means you can always find the hole at the top for your unlit rushlight even in pitch black; and it is easy to manipulate the stalk of the rushlight into a corner at the base.

The bobbles stop it slipping out of your hands, and potentially keep your hand away from the face nearest the expose flame.

#Dodecahedron

90 seconds traversing a musical dodecahedron at dodecahedron.newritual.com — 12 faces, 12 unique keys. This journey swings between Locrian darkness and Ionian brightness, switching from arpeggios to drones and back mid-flight. All 12 pitch classes visited. One of ~110 quadrillion possible configurations. #musictheory #dodecahedron #generativemusic #experimentalmusic #composition

This 2-min piece was composed on a musical dodecahedron at dodecahedron.newritual.com — 12 faces, 12 pitch classes, 7 modes. Each face holds a unique key. How many possible dodecahedra are there? Burnside's lemma meets music theory: ~110 quadrillion distinct configurations, after accounting for rotational symmetry. This is just one. #musictheory #dodecahedron #combinatorics #math #generativemusic #composition

"My name is David Dodecahedron."

"I've heard about you!"

"Where?"

"In geometry class."

"I hope the instructor was good."

"Oh, he was. Tasted like chicken, he did."

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.

Peeking inside the #dodecahedron in the `Museum der Illusionen Stuttgart`. Its endless black void is really inspiring.
