Sculpting with a chainsaw (PHOTOS)

For most people, the phrase "ice sculpture" may evoke images of melting swans and swanky dinner galas. But residents of London have a unique chance to learn the technique's creative potential, thanks to the annual London Ice Sculpting Festival, a celebration of ice and all the expressive possibilities it affords.

The festival, which commenced its fourth year Friday, appeals to everyone from casual observers to world-renowned practitioners of the frozen art. Festival events range from beginners' classes to timed competitions among teams from around the globe.
