Documentary captures a year of carving

Six weeks, 48,000 kilometres and 400 tonnes of snow; that's only part of what it took to document a year in the life of the Yukon's world champion snow carving team.

Filmmaker Thomas Balzer and cinematographer Dean Williams followed the team all over the world during 2007. The resulting film, Playing With Blocks, is out now.
