Peter Halley's *Triple 9* (2016) is a two-part canvas work executed in acrylic, fluorescent acrylic, and Roll-a-Tex, showcasing the artist's signature geometric abstraction rooted in social and architectural theory. The composition features Halley's iconic cells and conduits rendered in bold, flat planes of color, with the textured Roll-a-Tex surface adding a tactile, almost industrial quality to the work. The use of fluorescent acrylic infuses the painting with a vibrant, electric luminosity that reinforces Halley's ongoing exploration of the built environment and systems of confinement and connectivity.
