Ok, so there aren’t any adders in the video below, but I wanted to prime you for the other math- and snake-based puns that you’ll find. A friend of mine sent me a link to this video about mathematical doodles (and doodles done during math classes) which is filled with all sorts of geeky references and manages to show you some very cool tricks about drawing interwoven shapes.
I have a particular soft spot for math doodles because (1) I was a math major in college and (2) pretty much the only notes I kept from my classes were the ones with good doodles on them. Also, I did take topology but I couldn’t really tell you much about it anymore.
So, without further ado, check out this excellent video. Maybe you’ll even learn something!
