Driftwood, Screws, Timbers, Light
The stone shapes the ground. The ground holds up trees. The tree creates fresh water and air. That gives a life. All of things are related and affected each other. Human being is in the sequence and coexists with the balance of Nature.
The river shape and driftwood as they float from the mountain to the sea, is the metaphor of the sequence of Nature, and viewers will be in it.
