The Periodic Table of Storytelling
Stories make use of recurring ideas called "tropes" which repeat across genres and through time. The community at TVTropes.org catalogues these tropes in an enormous wiki, collecting examples for every imaginable trope with light-hearted glee. I created the Periodic Table of Storytelling as an introduction to TVTropes; it's an infographic that organizes the basic building blocks of storytelling into a familiar format.
