A man takes a picture of the one of the world's narrowest buildings, built as an artistic installation wedged between two existing buildings, in Warsaw October 23, 2012. A building just 92 cm (36 inches) wide as its narrowest point was opened in Warsaw on October 20 as an artistic installation that will be a home from home for Israeli writer Edgar Keret. Keret, who told news channel TVN24 he would live there when he visits Warsaw twice a year, said he conceived the project as a kind of memorial to his parents' family who died in the World War Two Holocaust.
