Joel Adler's Viewfinder periscope sculpture captures ocean waves at Sydney's Vaucluse lighthouse reserve

Australian artist Joel Adler has created Viewfinder, a permanent iron and mirror sculpture installed at the Vaucluse lighthouse reserve in Sydney. The work, first presented at a festival in 2019, uses refractive optics to give viewers the sensation of being directly above moving ocean water. Its periscope-like shape amplifies the sound of waves crashing against rocks. The installation is designed to immerse spectators in the hypnotic sound of breaking waves, wind, and the smell of sea salt.
