Outdoor sculptures that incorporate elements of process art festival displays are celebrated for their dynamic, interactive, and ever-evolving nature. These artworks often engage audiences in their creation or transformation, blurring the line between artist and viewer.

One iconic example is *The Gates* by Christo and Jeanne-Claude in New York’s Central Park. This temporary installation featured thousands of saffron-colored fabric panels, inviting public interaction and evolving with the environment. Another notable work is *Cloud Gate* (the "Bean") by Anish Kapoor in Chicago, which reflects and distorts its surroundings, creating a participatory experience.

Olafur Eliasson’s *The Weather Project* at Tate Modern transformed the museum’s Turbine Hall into a sunlit space, encouraging visitors to engage with light and atmosphere. Similarly, *Serpentine Pavilion* designs, which change annually, often incorporate process art principles, involving collaboration and improvisation.

These sculptures redefine public art by emphasizing process over permanence, making them unforgettable highlights of process art festivals worldwide.
