A giant, articulated steel Weta will represent New Zealand at one of the world's biggest outdoor art installation events. For 30 years, at the Burning Man, hundreds of artists from around the world build massive outdoor artworks - often several stories high - in the heart of the Nevada desert. Some are set on fire, while others stay on site or are sold off. But the Giant Weta will return to New Zealand. Lynn Freeman talks to Hippathy Valentine, this country's Burning Man representative who first went to the event at Black Rock City back in 2007.
