Leveraging the variations within a designed figure - the skin allows for high visual density and almost complete obscurity as well as open and porous conditions which can act as "windows" where desired. The skin changes with each face, with small apertures and built-in shades on the South and West sides, and large apertures on the East and North sides. Even within each face there is variety, and in some cases the skin presses outwards into a two-layer system.
