Spore 1.1 is a self-sustaining ecosystem for a rubber tree plant purchased at Home Depot. In this project, Home Depot is responsible for the plant in two ways: first, an unconditional guarantee to replace any plant they sell, for up to one year; second through an implied cybernetic contract. This second responsibility is the creative content for the work, where the economic health of Home Depot is transitioned through a series of physical computing techniques to a mechanism for controlling the watering of the rubber tree.
