Doodling — it’s usually a sign of boredom, an escape from tedium. Vi Hart turns it all upside down, and shows how doodling can be an engaging form of pedagogy. On her web site, you will find other math doodling videos called Stars, Snakes + Graphs, Binary Trees, Sick Number Games and Squiggle Inception. The video above is called Infinity Elephants.
