Tensegrity

The term was coined by Buckminster Fuller in the 1960s as a portmanteau of "tensional integrity".

Tensegrity, tensional integrity or floating compression is a structural principle based on a system of isolated components under compression inside a network of continuous tension, and arranged in such a way that the compressed members (usually bars or struts) do not touch each other while the prestressed tensioned members (usually cables or tendons) delineate the system spatially.

We decided to play with some wood pieces during the weekend…
Be honest: tensegrity is amazing!
