Curtain is a modular space divider designed with an experimental approach. The design inspiration came from my observation of the sea waves. I interpreted the spiritual energy in nature through the movement of the tides. Sea waves are boundless and directionless. I attempted to explain these two elements by creating a structure that allows unlimited extensions. The curves-only appearance stated the natural visuals of the sea. The structure consists of only two simple modules that allow stacking and are easy to assemble. The design outcome is a stable wavy structure that divides space with a hollow frame.
