      Each letter in this font is a <b>cube folding puzzle</b>:
      it is possible to fold the letter into a
      1&nbsp;&times;&nbsp;1&nbsp;&times;&nbsp;1 cube
      by <b>folding only along grid lines</b>,
      but doing so can be quite challenging.
      Each letter/puzzle is a rectangle with one or more <b>slits</b> (cuts).
      To try out a puzzle, cut out a rectangle and the slits indicated,
      precrease the grid lines, and try to make a cube.
      Every puzzle is designed so that at least one of the slits is
      <i>necessary</i>, meaning that the puzzle is unsolvable without it.
