It's stuff like this Japan! That really makes me think the people of your country don't work 90 hours a week like the stereotypes tell us you do. The setting, a beautiful wooded area with babbling brook and a serene peacful calm.

The project, build a wooden track through these woods so that a ball might roll down a hillside in a very controlled state. The result is amazing. At first you won't get what they are trying to do, but the more you watch and the more you listen it becomes quite apparent and even more spectacular.
