TV, desk and refrigerator. Industrial products are designed by many lines. The straight line is a prime example of the efficiency and uniformity in modern age.
Trees, flowers, grasses and cloud in the sky. The natural world are filled with lots of curves . Curved line is a product of the randomness.
But there is a exception and there is a straight line even in the natural world. This is surfaces in a pond or lake. The irresistible force of physical law makes the surface flat.
Many Japanese gardens have ponds. Three purposes to make a pond: 1. to play pleasure boating in a pond. 2. to walk around a pond and to enjoy the change of scenery. 3. to make the scenery around let in the surface of a pond. The clear water can reflect the scenery around like a mirror, and it roughly connects the world above the surface with the one below the surface.
The same holds true of the windows of the department store at night. Inside the window are displayed the autumn-winter cutting-edge fashion; on the surface are reflected the real scenery of the red or blue neon-glittering. In the window are crossing the ideal and the real, and the glass connects the ideal with the real.
The scenery can get the diversity at the boundary.
