Lumberjacked! allows game player to play computer games against Trees. By using the Tree Game Controller Unit (image below) it is possible to link a tree up to a pc or laptop and play specially designed games against it. The T.G.C.U. translates the movement of the tree into movement in the game.
Lumberjacked! was designed with trees in mind but can be played with any plant. For example, the developer of the game has played against bonsai trees indoors.
