More recently this research has continued with the idea of a digitally flexible system where the adjustability is handled within the parametric model, but now instead of the struts and connectors being separate pieces that are fastened together, the entire system is bent from one sheet of material. The starting point of the design was reducing the overall number of pieces. This evolved into a process of using as much of a sheet of material as possible without decreasing its spanning area. There is very little material that is not used within the structure, unlike the previous folded version with cut sheets which used less than half the starting sheet.
In Galileo's Dialogues Concerning Two New Sciences there is a passage where he describes the relationship between cross sectional area and bending stiffness. It's a fairly straightforward principle, and highlights the concept behind my favorite type of structural system; the space frame.
