I remember the eagerness of a clerk in a department store in Beijing. He was trying to impress us with their indestructible pants. Poking and pulling on them, lighting them on fire. He was young, and so seems the man in this video.

If you have ever seen the movie montage where someone wakes up and a convoluted mechanism makes breakfast, that describes this man’s life work.

A person could design an entire building with sunlight in mind. A person could also spend a long time designing some pots in the garden as this man has done.
