Yes, someone told us about this video when we first showcased this work. This video and a few more such works that we have discovered since then are linked in Q&A #7 in the readme. :-)
Congrats for this work! I haven't read the page far enough before commenting it seems (: Anyway, I hope this offered 13 minutes of fun to some HN readers
We don't have a good-quality recording of this that we could release. I have been looking forward to making one in the future. Thanks for the interest. :-)
Addendum: The text notes inserted within the Excel files partially cover for it, as that's roughy what the talk had, other than a possibility of live Q&A. The Q&A present in the readme is based on questions we have been actually asked. :-)
