During this afternoon's scheme design presentation, Sou Fujimoto explained how his acrylic tree structure, the Outside/Inside Tree has been greaty rationalised and simplified. Instead of being a curvilinear form, the structure will now be an angular abstraction of this previous proposal, consisting of hundreds of acryclic polygons bound together by cable ties. Here, in this film, Sou Fujimoto explains using a very simple concept model how the structure has evolved (the original proposal shown below).

As his new proposal seems to act almost like a tensegrity structure, I decided to show Fujimoto-san the Buckminster Fuller tensegrity model which we have in the V&A+RIBA Architecture Gallery - and we took a stroll up there after his presentation. He seemed intrigued..!
