Modern art installations are large-scale artworks designed to transform a space and engage viewers in unique ways. These installations often incorporate various materials, including sculpture, video, sound, and light, creating immersive experiences that challenge traditional notions of art. Artists use installations to express ideas, provoke thought, or evoke emotions, often encouraging interaction from the audience. Notable examples include works by artists like Christo and Jeanne-Claude and Yayoi Kusama, who create environments that invite exploration and reflection, making art accessible and relevant to contemporary society.
