Installations refer to large-scale artworks or structures created for a specific space or environment. They can include a variety of materials and forms, such as sculptures, videos, or interactive elements. Installations are often designed to engage viewers and encourage them to experience the artwork in a unique way, making the surrounding space an integral part of the piece. These artworks can be found in galleries, museums, or public spaces, and they often address themes like society, nature, or technology. Notable installation artists include Christo and Jeanne-Claude and Yayoi Kusama, who create immersive experiences that invite reflection and interaction from the audience.
