About Folium Folium is the result of a multistage digital growth process created by Nervous System based on L-systems and spatial colonization algorithms. Each design is one of a kind. The variably branched forms of the generated Folia range from round to tree-like. Some recall the dissected forms of maple leaves while others can be likened more to the branched forms of Chondrus crispus seaweed. Complex network patterns populate the interior of each Folium in several distinct styles that suggest leaf venation, city street grids, braided rivers, or other reticulations. Each specimen demonstrates a unique and dynamic interplay between its outer and inner growth systems with the result that no two shapes or patterns are alike.
