679 Cloud

I always think the colorful, (literally colorful) and elusive yet majestic way of cloud floating and flowing in the sky, is something that is unchanged through time and places. The sun, moon, stars and sky are the same in that way, but cloud is different because they don't usually show us the location, the direction, or the change of time. They appear in an unpredictable shapes and ways. Sometimes they cover the sky completely or sometimes they are comfortably blown in the wind. They are coming with rain and snow, or draw a grand picture in the sky highlighted with sunlight. Seen closely through the window of airplane, they seem like a living thing and cause me kind of a feeling of awe. We admire cloudless sky, but the world would be a less enjoyable place without them.
