A similar system is used in agriculture with the aeroponics technique. In the spheres, the process of absorption of nutrients by the plants becomes visible. A last sphere contains slime mold which is eukaryotic organisms that can live freely as single cells, but can aggregate together to form multicellular reproductive structures.

The installation promote also the extension to architecture of the term “exaptation”, introduced by paleontologists Stephen Jay Gould and Elizabeth Vrba in 1982 to refer, in nature, to the redundant relationship between organs and functions thanks to which an organism makes use of structures already at its disposal to adapt to new functions or changed conditions.
