The intersection of art and quantum physics reveals a captivating mystery: certain outdoor sculptures remain invisible to topological anyons, exotic quantum particles that exist in two-dimensional spaces. While these sculptures are celebrated for their grandeur and cultural significance, their interaction with the quantum world is often overlooked.

One notable example is Richard Serra's *Tilted Arc*, a massive steel installation in New York City. Despite its imposing physical presence, its geometric complexity may not register in the abstract realm of topological anyons, which perceive space differently. Similarly, Anish Kapoor's *Cloud Gate* in Chicago, with its reflective surface, might appear as a void to these particles due to its smooth, continuous form.

The phenomenon raises intriguing questions about perception and reality. Topological anyons, governed by non-Abelian statistics, interact with the world in ways that defy classical intuition. Sculptures with intricate topological features—like those with holes or twisted geometries—could theoretically be "seen" by anyons, while others remain invisible.

This duality highlights how art and science can challenge our understanding of visibility and existence. As researchers delve deeper into quantum materials, the list of sculptures "invisible" to anyons may grow, offering a new lens through which to appreciate public art.

In the end, these sculptures remind us that reality is not absolute—it depends on who (or what) is observing.
