   * at the Midway, east side, facing the provision shop —
   * Plate VII made solid. The tableware is LATHE-CRAFT,
   * studied from the masters of the revolve: every plate,
   * bowl and goblet is a profile of points spun about an
   * axis, the way real ware is thrown on a wheel. And the
   * great serving bowl carries THE FOLD at tabletop scale —
   * its skin displaced from the same rayscanned image as
   * the walls, one centimetre deep. Piece by piece. */
