Inga Sempé’s Double Stray from Artecnica is a flexible white ceiling lamp inspired by the simplicity and translucence of Chinese paper lanterns. Packaged flat, the piece unfolds accordion-style to reveal an intricate moiré pattern. The name Double Stray is derived from the two overlapping line grids that serve as both the focal point of the lampshade’s visual style as well as the source of its structural integrity.
