Spot of news for anyone who's missed what 
chefmongoose has been up to: he's been getting married. And this week had one of the people-getting-married nightmares: their wedding hadn't actually been booked and the venue wasn't available. On the old site he's got a slightly fuller explanation. The problem is it's way more expensive. Friends set up a GoFundMe, if you think you can do something to help a friend, or a friend-of-a-friend. Thanks.
So here's last week in my mathematics blog:

Some more puttering around at Pinburgh, on our free day.
I never knew what the deal here was, but these guys did look like they belonged there, and hey, The Motion Picture is my favorite of the Star Trek set, and I have altogether too vivid memories of Fangface for my health. Wouldn't this poster make for an incredible crossover fanfic? Don't look up Rickety Rocket.
Oh yeah, hey, Attack From The Back. What an Attack From Mars looks like from the platform high atop for reverse-game playing. It's amazing how fantastically wrong a game looks when you play from the reverse end, by the way. Just so creepy wrong.
One of a couple of free-standing posters in the hall: Did You Know that Mortal Kombat character Noob Saibot draws his name from designer Ed Boon and programmer John Tobias? Also that Ed Boon was the voice of FunHouse talking head Rudy? bunny_hugger sure did.
The playfield for electromechanical pinball game Blue Chip, presenting a fantastic vision of an impossible world in which the most financially important businesses are those which make steel, cars, refine chemicals, make pharmaceuticals, transport people and goods, and so on.
More evidence of bunny_hugger playing abnormally tall, and Python Anghelo-designed, game Big Guns. She recently put up the grand champion on another Big Guns at a barcade that just opened in Lansing, on her first game.
