|Vier gewinnt (12 struts, outlining an tetrahedron)|
I drafted the model with elastic string, using nylon for the 'base' of each tensul. It was tricky to balance, and untuned itself easily. Once I replaced all tendons, the model had movement as well as balance. I dread scaling the concept up, as the build was quite challenging with plenty of hick-ups on the way.
