An enormous aquarium with perpetually crashing waves has popped up amidst an urban landscape in South Korea, but don’t expect to hear the water sloshing around if you walk by. Designed by District, the elevated tank is actually a massive anamorphic illusion. The digital media company created the public project utilizing the world’s largest advertising screen that spans 80.1 x 20.1 meters. As shown in the video, the deceptive aquarium looms over the outdoor area and splashes repeatedly into the sides.
