Soil is a rich and mysterious world. Away from prying eyes, the Earth’s fertile crust is continuously changing. As a cross-section here, it remains hidden, contained by a wall. Nature Vivante (“Living Nature”) reveals the behind-the-scenes by projecting on this stone façade what it is holding back: the ground and its three horizons, i.e. the bedrock, the substratum and the topsoil. A picture that is painted one day at a time, while rain and sunlight liberate the organic matter — the seeds about to germinate — and the plant pigments contained in the pockets scattered along the wall. A living image, continuously modified by natural processes of erosion, oxidation and decomposition.
