Sapporo Snow Festival recently (as you do) and sent along a photo of Sweden's entry. It's a moose in a box.
The moose is cute but not that sophisticated snow-wise; however, the detail of the cardboard box is amazing. The box flaps and the crease in the corner are all rendered delicately out of snow. The moose placed second to Hong Kong's dragon entry.
