The structural system of topiaries acts mainly in compression and bending. Reversing this, a geometry that performs purely in tension is achieved. Designed as a single surface in tension, Vana hangs from the ceiling and descends as four columns of light. The surface is tessellated into triangular segments which are connected by stitched joints. Back lit with LEDs, light shines through the gaps and illuminates the space with an immersive glow. Vana performs as an iso-surface around an anastomotic network diagram, a cortex around a venation system.
