It's a copper buckyball (truncated icosahedron) and it looks so cool

Some years ago, I made a small icosahedron (maybe 1.5" diam) out of sterling silver wire welded together. Just a quick thing to practice some welds. The orange boys have, this morning, discovered it, and are batting it about the room gleefully.

icosahedron! and this wasn’t even from a bad ttrpg die roll

That's right, banish that treacherous icosahedron!
Condemn that one die (you know the one) to dice jail, forever! SHIFT RPG - Late pledges open! uses d4 through d12—we're not about that 20-sided life.

Repost with a photo of yours that would make a good album cover.

(This was one of the results of my final project in "Object Oriented Design" - I only had time to implement one primitive shape (sphere), but implemented intersections and both reflection and refraction)

Roman rock-crystal icosahedron (20-sided dice) used in fortune-telling.
Each face has a Latin letter on it and a corresponding Roman numeral, then matched with pre-prepared oracle answers in a divination handbook.
Currently at the Louvre.

あれ、Geometan’s Icosahedronって頭の両側についてるんだっけ

Once you see it, you can’t unsee it!

I think it puts this thread in better context too. I personalized a 1d20 di (ie. an icosahedron) so that I’d have a spatial representation (ie. a physical object) of Agrippa’s modes as dual positives and negatives.
Agrippa had five, according to Sextus, and the Modes largely correspond to the Pramanas of the Dharmic religions. Something interesting happens when you combine them into a Hasse diagram too.

If a = circular, then bcde are non-circular. If b is regressive, then acde are non-regressive. If c…etc.
