The Hexagonal Tiling Honeycomb

(Hyper)hexagons are the (hyper)bestagons https://m.youtube.com/watch?v=thOifuHs6eY

I wonder how this compares to H3. Why does H3 has pentagons as well, and this doesn't?

The, sadly not very polished, game Hyperbolica nevertheless really helped me open my mind to hyperbolic spaces.

This is cute, but I don't understand why it's on the arXiv. It's only two pages long, of which almost half is a picture and the bibliography, and as far as I can see contains nothing novel. I love Baez's blog(s) (https://johncarlosbaez.wordpress.com/ and https://math.ucr.edu/home/baez/), and it seems this would have been better served posted there as a post. Am I missing something?
