Once upon a time, a sultan set up a competition with a very rich prize for the most accomplished visual artistry. He invited teams from around the world. Both China and Greece sent delegations of artists. Each side could order whatever materials it wanted, and the wall of a room was provided for each to do its work. A curtain separated the two rooms.
The Chinese team asked for a plethora of paints made from many different plants and minerals, which provided an unimaginable array of colors. The Greek team asked only for materials for sanding and polishing.
When the two teams were finally ready, the Chinese unveiled their wall first. They had used every color of the rainbow, in a most harmonious design. The sultan was dazzled. Then the Greeks unveiled their work, throwing back the curtain between the two rooms. They had used no paint, but had polished their wall to such a degree that it reflected the work on the Chinese side. Through the play of light and air, the Chinese design seemed to move, and was even more fantastic and beautiful.
