After moving to a colder climate, I attempted to make ice on a sub-zero night by filling a small container with water. Water has the property of gradually beginning to freeze from the outside toward the center. One morning, by chance, I witnessed the process of water transforming into ice. It was a process of the growth of transparent crystals thinner than mica, pulling each other. The transparent crystals were not visible in the clear water, but once exposed to air and light, they revealed themselves to me in an instant. From that moment on, my observation and photography of ice began. Even under the same conditions, no two ice crystals appeared in the same shape, and I was amazed at the spectacular diversity of ice every day. The freezing process, which is like a microcosm of the diversity of the universe, is a mystery [secret ceremony?] that takes place at night when the temperature is below freezing. We hope you will join us for this ceremony.
