It was interesting to learn that in the early Zen monasteries all gardens were wet gardens, and that the transition to dry gardens resulted from war and/or economic upheavals. The Zen rock gardens were created to inspire calmness of the mind and to emulate the islands in the ocean. It was also interesting to learn how the gardens also served as foregrounds to backdrops of nature such as forests and mountains. I have recently replaced the wood chips around my house, and in part of my backyard, with small pebbles to emulate a Japanese Zen Garden. The simplicity of my new landscaping really does inspire calmness.
