All the creatures and human objects fossilised in the very last second of life and the world has since been covered with a thick layer of moon dust. Among all the destruction, some bits of new life emerge from the ruins. This is what I thought when I saw Adrián Villar Rojas installation, Today We Reboot the Planet, at the new Serpentine Sackler Gallery in London. All this destruction is not pretended, it is utterly real, as the material, unfired clay, is doomed. The clay, unless fired, cracks and crumbles when it dries, so, while it lasts, it has an amazing visual and texture quality. A series of ruins, buried architecture?, wraps the core of the exhibition, which was also the core of the former gunpowder store, an anthropological-museum-like room where all the fossils are displayed. Among them, new life is coming up in the shape of green shoots and sprouts. The brick floor is part of the installation and it is the only element that has been fired. However, it is also unstable and uneven, as the bricks have been laid loosely. This is the world, unstable and uneven though more permanent than us, the ephemeral creatures, the grey unfired clay that cracks and crumbles till it becomes dust again.
