Each letter is a glass cane, a cylinder of glass made by pulling and
    twisting an arrangement of straight lines of colored glass embedded
    within clear glass.  The top view shows the initial extruded arrangement,
    which is an easily recognized letter.  The side view shows the pulled and
    twisted result, as simulated by our
    Virtual Glass software,
    and forms a challenging puzzle to decipher.
    Another artist and friend, Helen Lee,
    made her own glass cane font
    (see Obfuscated Pangrams and Like Clockwork)
    using Virtual Glass.
