Throughout his career Herb Rosenberg has explored the visual poetry of illusion through many materials and media from clay and bronze to neon, water sculpture, glass and banana peels. For the past twenty years his work has focused on metals. The artist has written about this work: "The surfaces are flat. The medium is metal. The illusion is the treatment of the surfaces whereby they appear not to have surface boundaries. Instead that which is flat appears to have an illusive depth that changes as the light or the viewer moves. As a sculptor, I create these illusions, experiential illusions which trigger interactive participation with the audience. The steel and aluminum is transformed into soft, organic, energized images through a complex system of machining the metal with a variety of interlocking lines that refract light through a constantly changing array of angles. The surfaces appear deeply three-dimensional and holographic." The imagery created this way has been described by the painter Anneke Prins Simons as "emotions-in-motion' with their seemingly breathing movement capturing a glimpse of the human condition and its fragile beauty."
