Black Box by Takao Takenaka from japan

The telephone invented 150 years ago,
Successful wireless radio 100 years ago, and
Recent mobile phones and other IT infrastructure are spread rapidly.
Many of these mechanisms can not be grasped for a lot of people.
It is full of the black box in modern societies.
This art work have a question which we gain aspiration and insight about the sun & electricity.
When we enter the solar sculpture and look the sunshine,
it will bring us sun worship stories.
