Earth (2021), or “tierra” in Spanish, is a huge luminous sphere that emits light in a deeply intense hue of red. Caged within a metal structure built with scaffolding poles, the piece stands almost 25m high. Through the careful and deliberate design of the arresting piece’s form, color, and luminosity, SpY directs attention to humanity’s role in the planet’s cycles and changes. Visitors are invited to move around the installation so they can experience it both from afar and close up, and become actively engaged in the multidimensional experience. Earth was first installed in one of Madrid’s main squares in 2021 and became immensely popular, both in Spain and as a viral phenomenon.
