We can cut one of these open.

There's a gearing mechanism inside that's hidden from the public where you get a dot.

Yeah.

If you spin it, spin it ever so slightly, Joe.

Yeah?

That's nuts.

That's for you guys.

It's cool, right?

Yeah.

That's very bizarre.

All right, now my point is that one of the things that Terrence has going against him is people are saying, oh, you know, he's just playing with stuff people have played with since antiquity.

There's nothing new.

And then I would say, well, then why did Charles Haberman...

create a mechanism realizing the self-duality of the tetrahedron.

Nobody even talks about it that way.

And by the way, here's something that people play Dungeons and Dragons, they don't really even have any idea of, is if you take the five platonic solids here, and you put the tetrahedron in the middle, and you put the triangular structures of the octahedron and the icosahedron off to the sides, there's a duality

that interchanges the pairs with the center being self-dual.

In other words, the cube has six faces and eight vertices.

The octahedron has eight faces and six vertices.

The dodecahedron, 12 faces, 20 vertices.
