/*
 * The desk calendar (includes/pieces/desk.php): a flip calendar on a stone desk. A board-black backing
 * board, card leaves on steel wire rings, each leaf a month's payment (the day in big figures, the
 * month's little calendar with the day ringed in the group's colour, why it falls there). Leaves turn
 * up and over the rings (CSS 3D, hinged at the top). Beside it, the year as a timetable column.
