Tensegrity

Tensegrity is a structural principlal based on the use of isolated components in compression inside continuous tension.
It was invented by Buckminster Fuller and patented in 1962.
The tensegrity structure has been known as the largest and strongest structure per pound of structural material employed.
However it has been difficult to understand tensegrity structure only with texts and graphics for they can not express its 3D geometry nor the flow of forces.
This paper model however enables anyone to model it within one day and experience the unique characters of the structure.
