This is possibly one of the romantic cartoons I’ve ever seen. Just looking at it makes my heart crack. The character that XKCD calls “Megan” is dancing with pleasure, but her dance – by means of perfectly well understood and accurate (albeit exaggerated) physics – is itself altering the reality around her. Sheer beauty, and I feel the ache of young love just to look at it. (Your milage may vary, of course).
