Inside the hexagon, iconic scenes and moments from the novel "Moby Dick" unfold.  Small visual representations of the Pequod whaling ship, the grim Captain Ahab, and the majestic and fearsome white whale, Moby Dick, can be seen.  The ocean, both beautiful and dangerous, covers much of the bottom, with waves that seem to move and crash against the ship.   In one section, Ahab's obsession is depicted, symbolized by his harpoon and his ivory leg, constant reminders of his vendetta against Moby Dick.  Another segment could contain the various members of the Pequod's crew, from the narrator Ishmael to the wise harpooner Queequeg.   The center of the hexagon could be dominated by the image of Moby Dick, rising from the ocean with a powerful jet of water.  Each element has been carefully selected to capture the essence of adventure, obsession and tragedy that define "Moby Dick."
