Polish historians have created an unusual 3D film that documents the shocking sea of rubble that Warsaw was reduced to during World War II. Jan Oldakowski, the director of the Warsaw Uprising Museum, says it is mainly meant for young people who do not realize the degree to which Poland's capital was destroyed from 1939-45. Specialists used historic images to create a computer simulation of a flight over the city in early 1945 that shows collapsed bridges, districts of roofless, burned-out houses and the Warsaw Ghetto as a flat sea of rubble.
