The stripe on the sand, at Ginkakuji Temple, in Kyoto

The stripe is a part of the object in a garden of Gingakuji Temple, one of the main attractions in Kyoto. The pattern is drawn on the sand just close to a small pond and means the water surface. The sand is said to contain more a-kind-of-quartz than usual and shines slightly at night by the full moon, though it is unfortunately closed at night and we cannot see it.
