Animations largely made using manim, a scrappy open-source python library.
https://github.com/3b1b/manimIf you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and has many other quirks you might expect in a library someone wrote with only their own use in mind.

I really appreciate those who do this, as it helps make the lessons accessible to more people.
