Over two years, a group of Japanese high school students has been painstakingly producing a five-minute virtual reality experience that recreates the sights and sounds of Hiroshima before, during and after the US dropped an atomic bomb on the city 73 years ago today.
By transporting users back in time to the moment when a city was turned into a wasteland, the students and their teacher hope to ensure that something similar never happens again.
To recreate Hiroshima, the students studied old photographs and postcards and interviewed survivors of the bombing to hear their experiences and get their feedback on the VR footage. They used computer graphics software to add further details such as lighting and the natural wear and tear on building surfaces.
