Rocks are postcards from our geologic ancestors. A floor-plan through which we can get in touch with the history of the universe, our most ancient birth. The language of rocks is time, the language of nature is geometry. But man lives in chaos. His struggle is to overcome it, reorganize it with his means. Ancient codes pass through looms, they allow us to reorganize chaos in order to understand the world, and maybe even to reply to those postcards.
