New Brighton beach in Christchurch: Peter Donnelly is busy creating art, art with a lifespan that can be measured in hours. Using a rake and a piece of wood, Donnelly draws elaborate artworks in the sand - more than 700 of them to date. "I bring something to life, and then its life is over, and at the end of the four hours it wants to go, it's worn out ... it just wants to be gifted, and it goes to the sea." Beautifully shot by director Peter Young, this Artsville documentary captures Donnelly both in action, and musing on the beauty of impermanence.
