Outdoor sculptures that incorporate vacuum fluorescent displays (VFDs) are rare yet fascinating intersections of art and technology. These installations often merge light, motion, and interactivity to create immersive public experiences. One notable example is *"The Weather Project"* by Olafur Eliasson, which used VFDs to simulate atmospheric effects in London's Tate Modern. Another iconic piece is *"Pulse Park"* by Rafael Lozano-Hemmer, where VFDs responded to visitors' heartbeats in New York City.

In Japan, Tatsuo Miyajima's *"Counter Void"* employed VFDs to display counting sequences, symbolizing the passage of time. Meanwhile, *"Light Matrix"* by Jenny Holzer in Las Vegas used VFDs to project poetic texts onto buildings, blending urban architecture with digital art.

These sculptures redefine public spaces by inviting viewers to engage with art dynamically. Their use of VFDs not only enhances visual appeal but also bridges the gap between traditional sculpture and modern technology. As urban landscapes evolve, such installations continue to push the boundaries of interactive art.
