  Topological insulators are insulators in the bulk but feature chiral energy
propagation along the boundary. This property is topological in nature and
therefore robust to disorder. Originally discovered in electronic materials,
topologically protected boundary transport has since been observed in many
other physical systems. Thus, it is natural to ask whether this phenomenon
finds relevance in a broader context. We choreograph a dance in which a group
of humans, arranged on a square grid, behave as a topological insulator. The
dance features unidirectional flow of movement through dancers on the lattice
edge. This effect persists when people are removed from the dance floor. Our
work extends the applicability of wave physics to the performance arts.
