Vi Hart, my favorite narrative doodler, has produced two more wonderful videos, and you should watch them. Right now, if you can.

Now here’s my question: I love these videos, but I’m also a mathematician, so I know of most (but not all!) of what she’s doodling. So to those who aren’t as familiar with what she’s playing with: do these videos make sense? Are they fun? Are they clear? Do they make you want to play, and know more?
