We are having some calamitous (for Virginia) weather lately - an astonishingly brutal winter altogether so far, in fact.  I'm told the kids are calling it "Snowpocalypse," or "Snowtorious B.I.G."   So I thought it would be nice to shamelessly mooch off some splendid research done by one of my colleagues and bring you a snow-themed post in honor of this snowy weekend; something to do for about 3 minutes while you're snowed in, or, if you are not snowed in, something to feel real good about.
