The light around the base of the sand table corresponds with the light above, as if a light loop with no beginning and no end. The lines in the ceiling resemble high-speed moving star tracks, representing the dynamics and rhythm of the universe. The wide use of glass as walls breaks the separation between indoor and outdoor space, and introducing natural light and scenery into the room. The combination of light and bookshelf creates a perfect light and shadow effect, and avoids the clutter at the same time, making the space look elegant and modern.
