If you're like me, your first thought was, "wait, how did they tile a sphere with hexagons?" And then you notice the pentagons. I think it's actually a Golderg icosahedron, which is the dual of a geodesic sphere. (And which, incidentally, would have made the Well World map way less stupid.)
It kind of feels like my "Splodesic" screen saver came to life!
Old football (soccer) balls used octagons and pentagons too. Many people (and several websites cites this as a fact) actually believe Buckminster Fuller himself designed this model, but sadly that's a myth.
For both soccer balls and the displays above, it's a trip to actually notice the pentagons when your eyes actually focus on them. (From 2018:)
It will hatch soon.
Props for the Well World reference. I loved those books, haven't thought about them in years.
They're, uh..... not as good as you remember.
And apparently the reason there's no online map or 3D model is because his map was bullshit.
I'm sure they're exactly as good as I remember, as I don't have very good taste. The Four Lords of the Diamond? The Dancing Gods? Loved them! And he has so many books I never read...
