@ZenoRogue (author of HyperRogue) tweeted an interesting surface
made by gluing
together 6 heptagons earlier today. It has 6 faces, 21 edges, 14 vertices,
and Euler characteristic -1. There is a discussion of this surface here
.

Using his picture, I configured the gluing map for MagicTile, so there are
new {7,3} puzzles to play with. These should be pretty fun! You can see an
image here and
download the latest here .

Cheers,
Roice
