Swimming Pool by Leandro Erlich is an art installation conceived in 1999, Swimming Pool allows visitors to look down into a seemingly full pool of water with fully clothed visitors walking around the bottom of the pool. From below, the blurry vision of looking up when underwater is recreated using a thin piece of glass with water running over top of it. Complete with a climbing ladder, swimming pool is a fun and interactive installation that creates the illusion of being underwater whilst remaining completely dry.
