Today, I came across something—or, more appropriately, somone—that I can only describe as extraordinary: the charismatic and charming “mathamusician” Vi Hart. Vi is a musician with an interest in recreational mathematics (i.e. math done for fun). Of special note are her videos on doodling in math class. Not only is her critique of mathematics curricula spot on, she sneaks in some fascinating mathematics. If you teach math, or are interested in math, go have a look.
