Finished a post today on chords. It would be really easy to keep going and make a Monte Carlo for random chords, rotations of connected shapes, moire strings, shadow art with strings, etc.

An aperiodic tessellation of the hyperbolic plane, found by Toimine in the #tessellations channel in the HyperRogue discord.
These tiles have edge length of 0.56358, less than the previous record for a equilateral convex tile (0.56626, achieved by the regular {7,3} tiling).

Star a la Fujimoto III (back), folded from Julia Schönhuber’s patterned paper. The symmetry of the pattern matches the model.

In order to make this origami star, you need a piece of paper in the shape of a regular pentagon. There's a standard method of cutting a pentagon from a square piece of paper. The interesting thing is: it is only an approximation! www.youtube.com/watch?v=ezQV...

8675309 is prime, and so is 8675311, so if you ever need a middlin'-large pair of adjacent primes to test your cryptographic suite, all you need is a 1980s earworm and a +2 and you're all set.
Man, everything is so bleak, anyone got a fun fact or little bit of trivia they want to share
