Japanese origami artist Wataru Ito spent four years constructing an intricate cityscape using only craft paper, glue, an art knife and holepuncher. Ito's 'Castle on the Ocean' is currently being displayed at an exhibition on the artificial island of Umihotaru. "When the exhibition is over I will burn the castle. I thought I could see it rising up from the ashes if I took a video and played it backwards," Ito said. More photos at The Telegraph.
