Generate a highly detailed image of a complex, abstract sculpture, fluidly composed of highly reflective, polished liquid metal, resembling molten chrome or iridescent mercury. The form should convey constant, graceful motion, with smooth undulations, merging tendrils, and ephemeral shapes that appear to be perpetually shifting and reforming. Capture the dynamic interplay of light across its surface, creating intense reflections and specular highlights against a deep, contrasting background, evoking a futuristic and mesmerizing aesthetic. Use a dramatic low-angle perspective to emphasize its grandeur.
