A virtual wave appears to crash and roll around a huge tank in an installation in Seoul, South Korea.
The mesmerizing creation is described as an "anamorphic illusion" and is visible on the world's biggest outdoor high-definition screen.
The wave simulation, titled Public Media Art #1 Wave, was created by agency d'strict on a 1,620sq meter smart screen using Samsung smart LED technology, which is said to have an area four times the size of a basketball court.
Now the aquarium has more than 230,000 YouTube views, with one user saying it was a "reminder of the forces of nature in the middle of a city."
