If you've seen any global warming disaster movies, they always include some city being engulfed by waves of water rushing in from the nearby coast. Take The Day After Tomorrow, huge waves smash through the streets of New York and there's the obvious London disaster movie, Flood in which water rises over the Thames Barrier to cover the city.
But what would it be like the morning afterwards, when the watery city had settled? Filmmakers Olivier Campagne (of effects visualisation group ArteFactoryLab) and Vivien Blazi have tried to imagine it with their short film 5:46am. Take a look, it's eerie, but quite beautiful.
