Have you ever seen a city built entirely from Ice_

For a few months each winter, Harbin, China, turns into a fantastical "city of ice." From January 5 through February 25, this chilly provincial capital plays host to the Harbin International Ice and Snow Sculpture Festival. Artists create an incredible display of large-scale sculpture, architecture and design built entirely from snow and ice. The spectacle may be temporary, but for award-winning ice sculptor Jinnan Zheng, the preparation begins long before the first snowflakes fall.
