And you thought your neighbor's Christmas lights were impressive. The Harbin International Ice and Snow Sculpture Festival is home to one of the world's most spectacular displays of wintertime outdoor illumination. Located in the Heilongjiang province — not all that far from Siberia — the temps at this month-long event are typically well under 0ยบ C, but make possible the massive snow sculptures at Sun Island, and the main attraction, Zhaolin Park's Ice and Snow World, with huge ice and snow buildings that are lit up using everything from ice lanterns to lasers.
