Hey guys,
This project got me fascinated a few years ago (firstly because of the sci-fi-esc columns). Manufacturing is by means of 3D-printing with concrete, using robots. In my opinion, it is interesting on the topic of ornamentics due to the structural characteristics which could also be said to be decorative.
