Outdoor sculptures that incorporate periscopes offer a unique and interactive way to experience art. These installations challenge viewers to engage with the artwork from unconventional angles, often revealing hidden details or perspectives. One of the most famous examples is *Periscopio* by Argentine artist Julio Le Parc, located in Paris. This kinetic sculpture invites passersby to peer through a periscope, transforming their view of the surrounding urban landscape into a dynamic visual experience.

Another notable piece is *The Viewer* by American artist Tony Tasset, installed in Chicago. This large-scale eyeball sculpture features a periscope inside, allowing visitors to see the city from a surreal, elevated vantage point. Similarly, *Periscope Pavilion* by Dutch designers at MVRDV in Rotterdam uses mirrored periscopes to create playful distortions of the skyline, blending art with architecture.

These sculptures not only serve as public art but also encourage interaction and curiosity. By merging technology with creativity, they redefine how we perceive and engage with outdoor installations. Whether for aesthetic pleasure or intellectual stimulation, periscope-viewed sculptures remain a fascinating niche in the world of public art.
