#dodecahedron — Public Fediverse posts

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.

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

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.

@rasjor @nanma80 Geogebra has a Net tool/command, but it lacks flexibility -- I guess the dedicated could edit the source code

@mrdk @unnick And here’s the rhombic triacontahedron for the dodecahedron/icosahedron (again without scaling the bars to have constant length).

I couldn’t resist making this in Geogebra: morphing between a regular icosahedron and a regular dodecahedron.

Some bedtime reading for you all: why access to artefacts and the free ability to research, publish - and replicate - matters.

I love dodecahedrons, okay? And I am upset that Mathstodon is underlining that word. Perhaps I don't have the right dictionary installed

@AlecSteele why would YOU make so many of these?

#TilingTuesday Dodecahedral tangle.

If you intersect 3 golden rectangles, their corners can form a regular dodecahedron! But what if you extend the tiles to S shapes and then impossibly tile those?

And once again I've seen a gem for the #WeirdCarMastodon crowd, this time a very odd #caravan or maybe a #tinyhouse in the form of a #dodecahedron!

after losing my mind because all code was "hidden" in a different branch, I decided to swap the NRF52840 for an ESP32 board. Now I can finally run I2C on 1MHz and have an FPS of 39 instead of 15. #dodecahedron
