Inspired by the basic concept of Newton’s Cradle: five spheres with same weight hung side by side closely together, pushing and swinging back and forth on the sides. The perpetual swinging demonstrates the conservation of momentum, as if five spheres work together to transmit the force. Its concept symbolizes how family members interact with each other in the living environment. Home, is the medium where energy flows, going back and forth between people. Its rhythm, lines, concept, are interpreted by round and smooth lights, curved and oval shapes.
