The Moon
I believe that lights can act as a company to the people who lives in a city where space is limited. It's very easy to feel lonely. The moon is designed in this contexts.
The has a warm ambient light, you can control the moon to wax, and to wane.
When this person arrives home from work, she can take the moon globe and use as a movable lighting. With the "full moon", it can be used as a reading light, when it's the time to sleep, the crescent can be served as a mood light.
