Apart from the 2016 Christmas Tree lecture [1] (which is even available in 3D [2]), Knuth also mentioned this “mysterious package from Poland” during an earlier (a week earlier) lecture at Brown University [3] (about 25 minutes in).<p>I love this talk (he gave roughly the same talk at both places, though one was more rushed than the other). He goes pretty deep into history — for example his discussion of Hamiltonian tours (knight's tours etc.) in Sanskrit poetry is at a level of detail that I have not seen in any other published source in English. After knowing that he was interested in this topic, I requested a contemporary Sanskrit poet to write a “knight's tour” Sanskrit poem, and gave it to Knuth as a gift. He loved it!<p>[1]: <a href="https://www.youtube.com/watch?v=DjZB9HvddQk" rel="nofollow">https://www.youtube.com/watch?v=DjZB9HvddQk</a><p>[2]: <a href="https://www.youtube.com/watch?v=9DrzK3Z0rg0" rel="nofollow">https://www.youtube.com/watch?v=9DrzK3Z0rg0</a><p>[3]: <a href="https://www.youtube.com/watch?v=4UFkH5ZlVqQ" rel="nofollow">https://www.youtube.com/watch?v=4UFkH5ZlVqQ</a>
Retrospectively considering "It would be nice to own a 3D-printed object like this!" as an understatement (i.e. a "mistake" in his book) was a clever hack to create an excuse for giving them one of his famous reward checks. And kind and hilarious to boot! Prof. Knuth is amazing.
Nice one, congrats!<p>(Also imagine my surprise, seeing my home town mentioned on the front page of HN this early morning! I thought for a second that sleep deprivation finally got the best of me.)<p>I wish you best of luck. I used to be in the Kraków's 3DP commumity back in Materialination heydays. That was before you were founded, but maybe we've crossed paths there.
It looks like they got the N upside-down. The top of the N (the end with two serifs, as you can see here <a href="http://www.identifont.com/similar?TI" rel="nofollow">http://www.identifont.com/similar?TI</a> ) is pointing to M, rather than the bottom.
Of course this is exceedingly cool and the item itself is of good quality, but it should be said that it's possible to make your own twenty-sided dice with whatever you want on their faces, by ordering blank dice on the internet and painting your desired symbols by hand. There's also companies that can print you the diece you want.<p>In fact, gaming lore says that in the early days of pen-and-paper RPGs, gamers couldn't find anyone selling the polyhedral dice they needed, so they ordered instead Platonic solids used for demonstration of geometric objects' properties from school supplies retailers and filled in the numbers by hand, as above. Which in no way means that any early d20s were missing a few 1's and 2's :|
FYI Prof. Knuth presents the problem at 16:50 into the lecture[1] linked in the blog, then shows off his Sinterit trinket at 18:30ish.<p>[1] <a href="https://youtu.be/DjZB9HvddQk?t=1010" rel="nofollow">https://youtu.be/DjZB9HvddQk?t=1010</a>
Very fun.<p>I didn't know what a Hamiltonian graph was:
