This structure is inspired by the forces of nature that drive the formation of complex networks. (both physical and behavioral networks) 
From the nano-scale Actin filament networks of cells to the ultra mega macro webs that make up the universe, nonlinear networks play a central role in everything. I designed this branching system to help visualize and better understand how networks grow and evolve.
The green glowing elements indicate dendritic branching events. note: the branching events form concentric layers within the spherical structure. This layer/shell structure emerged from the parent structure.
Non-linear network structures are physically strong and have an important role in future of structural engineering.
