My interest lies in the act of human beings sculpting the nature, displaying an objective aspect by transforming its shape, visualizing and reaffirming the value of what is overlooked. With a half of the 7m moon mirror, I created the dwellings of this city in the 1:100 scale, likening the cluster of mirror houses to crystals. Another half-moon is cut up into a map of the city where the exhibition takes place. The material quantity of the half-moon and that of the houses made from the other half both equal each other; hence, all of them evidently belong to the same phenomena. In light of this, I explore the responsibility and meanings of my act of sculpting.
