@ZenoRogue (author of HyperRogue) tweeted an interesting surface
<https://twitter.com/ZenoRogue/status/1009502362816434180> 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
<https://steamcommunity.com/app/342610/discussions/1/3051633726580659909/>.

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 <https://twitter.com/roice713/status/1009573106049015809> and
download the latest here <http://roice3.org/magictile/>.

Cheers,
