Plus Advent Calendar Door #2: Vi Hart's hexaflexagons!

Here at Plus we love everything Vi Hart produces. But her recent series on hexaflexagons (suggested by our good friend Sharon) is superb! In addition to the history of these mathemagical objects and how to make them (part 1 and part 2) there's a hilarious Hexaflexagon Safety Guide and our favourite, Tex Mex Hexaflexagons! Enjoy!
