You have much to learn, dear reader. Settle in — it's arts and crafts time. Let math-craft-wunderkind Vi Hart expand your mind with this captivating tutorial on snowflakes, starflakes, and swirlflakes.
Last week, YouTube's resident mathematical mind-blower, Vi Hart, introduced many of us to the topological wonder that is the hexaflexagon. If you haven't seen it yet, get your life in order and go check it out. In fact, even if you have seen it, go ahead and watch it again. Then reconvene with us here for round two…
