"Echoes of Reflections" and "Shadows of Reflections" are mainly inspired by the "Porcelain vase with a rotating interior and decoration of fish in a cobalt blue glaze" and the "Yi with animal-shaped handle and legs in the form of human figures" of the NPM's collection.  "Echoes of Reflections" presents a replica of the "Porcelain vase with a rotating interior and decoration of fish in a cobalt blue glaze" from the Ch'ien-Lung reign. However, the replica does not copy the colors, it is only a white vase. This vase is placed on the surface of a table, naturally creating a reflection in the table's glass surface; but the white reflection gradually changes into the original colors of the vase, and then back to white again. The mirror image reflects an echo of past to present. The other piece, "Shadows of Reflections", places an actual reproduction of the "Yi with animal-shaped handle and legs in the form of human figures" on a table with a dark glass surface, again creating a natural reflection. In it the people depicted on the Jug begin to walk, and the beasts begin to stir; and sometime ripples surround the bottom of the vase. The images are like reflections, still, yet moving, projecting a shadow of past to present.
