The installation is structured around three themes, all related to tunnels:

* the mining tunnel, which refers to miners in Central Africa, particularly in the DRC, who work in appalling conditions and whose children are shamelessly exploited.

* The tunnels dug by Elon Musk in the United States. He uses magnetic levitation, a physical phenomenon that allows very high speeds to be reached (already used in Asian countries).

* wormholes, which scientists believe are tunnels that would allow travel from one universe to another
