I’m currently having terrific fun playing around on Jeff Weeks’ flight simulator, Curved Spaces. Unlike most flight-simulators, the action takes place not in regular Euclidean space, but in a selection of 3-manifolds. (It’s also comforting that you don’t have to worry about crashing.) Highly recommended!

Should you not be spending time writing so that you have time to attend special events at other peoples’ houses?
Believe me, I am spending a lot of time writing.
Hi again, people; greetings from Shanghai!!!
What fun! Being slightly more violently-minded, I have for a long while wondered if there is a version of DOOM or some similar computer game in hyperbolic space…it would be fun to try to program such a thing, if I had the time, but unfortunately I don’t – the joys of employment!
