The idea behind this project began with the Menger sponge. Steven Holl references the menger sponge in his Sarphatistraat offices and it introduces the concept of porosity. “The layers of perforated screens are developed in three dimensions, analogous to the “Menger Sponge” principle of openings that are continuously cut in planes and constantly approaching zero volume.”

Taking the idea of porosity further.. what if the child cubes were exposed on all 6 faces?

BRANCHING rootTree = cone() to box() height, radius1 radius2 become redundant rotation fixed to 90 offset set to 1 - can be extended to create non-connected cubes branch depth, min and max remain variable and allow for random generation
