This membrane model investigates how tension, rotation, and compression can produce architectural form through a central vertical spine. Each vertebra-like plate rotates at fixed 45-degree increments through an internal cog system and receives sticks of two lengths, 3 inches and 2¼ inches. A stretched spandex membrane is pulled over the assembly, allowing the volume to emerge through a three-dimensional form-finding process.

The first two variations keep the stick arrangement fixed and transform the form through rotation alone. Later iterations alternate stick positions and lengths, creating concave conditions, changing silhouettes, and more articulated spatial effects within the spine and membrane system.
