The Vancouver Biennale, a bi-annual public art exhibition that "turns the city into an open-air museum," is featuring artist Konstantin Dimopoulos’ "The Blue Trees" this year in 2011. The installation is a set of trees that have received a rich yet enviromentally-safe "temporary colourant" designed to fade gradually over the course of a few weeks.
The painted trees are actually newly planted just for this exhibition, which is a big plus for the city. Residents of the Richmond neighborhood get to keep the set once the blue vanishes. The artist says this is "an afforestation art action set within an urban context."
Also, volunteers and loaned paint equipment made the installation fairly low-cost and simple
Egypt-born Dimopoulos is based in New Zealand where he has created Pacific Grass, a wind sculpture, as well as his well-known rod sculptures.
