Artist Dan Young offers a thought-provoking opportunity to test your wits against Mother Nature. He has developed video games, "Lumberjacked" and "Lumberjacked II", which allow a tree to be outfitted with digital sensors feeding to software which interprets the tree's natural movements into defensive moves against Jack the Lumberjack or Jackman (ala Pacman). To make the game a little more fair, it is best if you use a wild plant or open a window near your potted plant, otherwise the timescale of your opponent's natural movements put it at a real disadvantage. Now you can live out scenes from "Lord of the Rings" in human time. Dan Young is challenging man's relationship with nature at exhibitions, with videos and at his website Lumberjacked!
