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.

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)
A ray-traced image of 12 blue and green half-spheres arranged like the 12 corners of an icosahedron. The "half-spheres" are actually smaller spheres all intersected with a large sphere centered at the center of the icosahedron. In front of the half spheres hovers a clear glass sphere visible only in how the parts of the image behind it are refracted.

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.

I'm going to post a few from the festival last night, but this might be my favourite since it looks like a classic fantasy paperback cover

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.
thutmose.bsky.social Crown Prince Thutmose @thutmose.bsky.social · Dec 8
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.
