Michael said the Rain8 might be an interesting addition to a garden.
Rain8 - X10 Sprinkler Controller: "The Rain8 is a full featured, 8 zone irrigation controller that may be linked together to provide a maximum of 256 zones of operation. A must for automating lawn sprinkler systems. A complete irrigation schedule can be triggered by the reception of a single X10 power line carrier command. With its dual mode capability, each individual zone can be controlled independently if the user prefers. Using a PC and our software all aspects of irrigation may be controlled over the Internet. "
