Frost grows on the window glass, forming whorl patterns of lovely translucent geometry.<br /><br />Breathe on the glass, and you give frost more ammunition.<br /><br />Now it can build castles and cities and whole ice continents with your breath’s vapor.<br /><br />In a few blinks you can almost see the winter fairies moving in . . .<br /><br />But first, you hear the crackle of their wings.
