A boy in my old memory bought a kaleidoscope at the night market. In the smell of carbide and the light of flickering acetylene, the art of light that changes one after another when the tube is turned, yet never repeats the same pattern. Did that make the boy spend what little pocket money he had?
But in the tube even more than its fantastic beauty. What aroused the boy’s curiosity even more strongly was. It was the mechanism inside the tube. Patterns that appear endlessly one after another. It is born by multiple reflections with only three mirrors. The ever-changing natural world is also governed by a few very simple basic laws.
