Cliff Stoll here. The brand hijacking on Amazon USA was fixed. But Amazon Canada listing is still held by Amvoom. I'm unable to sell Klein bottles in Canada.

Hey Cliff, just curious: how were you made aware that this post on HN is trending?

  Hi Matt, All of a sudden, I got three or four Klein bottle orders. That's a lot for an hour! One of the orders (thank you Bryan in Johnstown) mentioned Hacker News. And, well, here I am.

      He hasn't for quite a while afaik, way too time intensive to build by hand so he (at least last I saw 10 years ago) had a big batch made by a glass blowing company.

        Yep, I no longer make regular Klein bottles. I'm a so-so glassblower. (Indeed, most glass workers would consider me a good physicist. Physicists would say that I'm a good computer jock. Computer people think that I know a lot about math. Mathematicians feel that I'm a good glassblower. Keep 'em all guessing.

Are you still using the little forklift robot from the Numberphile video? https://www.youtube.com/watch?v=-k3mVnRlQLU https://www.youtube.com/watch?v=-k3mVnRlQLU

  Yep, Ritkew ... that homebrew forklift helps pull boxes of glass manifolds every day. The crawlspace is maybe 2 feet tall, and I don't like crawling around there. It's how I cheat my chiropractor.

  Man, I enjoyed this so much. I love seeing people who just get things done, aren't too picky about solutions, and demonstrate ingenuity like this. I really admire it. Making things work with what you've got is an amazing skill, and something I need to work on more. I always want things to be 'just so' and I fail to appreciate how awesome things can be, even if they aren't perfect.
