This is absolutely delightful. I can take no credit for the following chart, but I wish it had been my idea first. Someone has made a periodic table listing various tropes of storytelling, and, althrough it is largely intended as a joke, it can serve as a strikingly accurate way to describe any number of stories, diagramming them like molecules in chemistry. Don’t believe me? Check it out for yourself.

I want a poster print of it to hang in my English classroom.
