The complexity of the system lies in its geometry. The rings of the oblique cone form ellipses as they enclose the supports made of hollow profiles. Imitating the shape of horse tail stems, the supports taper by steps toward the top.

The point supported insulated glass panels had to be cut into many varying shapes to fit the geometry.
