Post your favorite polyhedra

I know it's vanilla, but mine is the regular icosahedron. Can't go wrong with a classic.

Almost ball with finite number of points, where there are triangles going inside the ball with increased diameter as they go inside in a way it stops just right so there are triangles on the outside on a tip of a needle.

With total surface really big, surface of the outer ball bigger than surface of inner ball.

Are the Platonic solids just memes or is sacred geometry unironically fucking rad? (I think it's the latter and I don't even care about your opinion of me)

"sacred geometry" is very very silly, but those shapes are objectively cool as fuck.
I would say that any mathematical construct that, despite having very simple and non-specific constraints, produces a higher than 2 finite set of results is pretty dang awesome.

> The grand 600-cell can be seen as the four-dimensional analogue of the great icosahedron (which in turn is analogous to the pentagram)

Mine is tingling from the chip the government put into my wrist, I've been trying to cut it out for the past 15 minutes. Seems they put it pretty deep though.
