When the atomic bomb hit Hiroshima, people's shadows were permanently scorched in to their surroundings. Rikako Nagashima and her team contacted 23 survivors and took copies of their shadows. They then placed these shadows around Hiroshima as a memorial and to spread awareness of what happened. From Peace Shadow Project's website we can see where these survivors were, hear their stories, and leave them a personal message. (in Japanese with English subtitles)
