Some animations in my videos are done by William Marler who is the same person who does animations for Tom Scott. I think Tom and I both met Will at the Royal Institution Christmas Lecture filming in 2019 (for which Will also did the title sequence).
Anyway, Will has put out a video showing where he has hidden all sorts of ridiculous jokes and references in our videos. Some of which we knew about. So this is not an exclusive video at all, but I thought you might like to see it and I'll answer any questions about the Easter Eggs in the comments!
For the record: I came up with the cuneiform pictographic translation of "Humble Pi" as "stand mouth, nourishment bowl". Let me know if you can do better!
