Outside the Royal Festival Hall of London, you can play in these rooms created by walls of water. It's really good fun but beware when the wind changes as you can get wet!
Danish artist Jeppe Hein's aquatic sculpture Appearing Rooms was originally commissioned for the garden of the Villa Manin, Italy. Inspired by the Baroque villa, he designed an ornamental fountain that combines sculpture, architecture, and technology and playfully invites visitors to interact with the changing spaces created by rising and falling walls of water.
