CoralArc utilizes algorithms to simulate the rules of pushing, replicating, and growing among tiny cells. After dynamic stacking along the time axis, it forms a complex organic curved surface. The work utilizes transparent materials to express the beautiful changing form and pure luster of undersea corals, while its colors are the coexistences of the people interacting with the lights, as well as the scenery on the beautiful bay. Through the properties of material, it echoes the endless coastline and sky when the viewer looks out at the sea, and shows various appearance in different periods.
