Q-balls, theoretical quantum objects, have inspired a niche yet fascinating genre of outdoor sculptures. While not widespread, a few renowned artists have incorporated the concept into large-scale public art, blending science and aesthetics. One notable example is "Quantum Flux" by sculptor Elena Velez, a towering stainless steel installation in Barcelona that mimics the dynamic energy of Q-balls. Another is "Cosmic Resonance" in Tokyo’s tech district, where interconnected spheres symbolize quantum entanglement. These works challenge traditional sculpture by visualizing abstract physics, attracting both art enthusiasts and science admirers. Though rare, Q-ball sculptures redefine public art with their futuristic appeal and intellectual depth.
