Motoi Yamamoto is a Japanese artist creating a name for himself by making intricate, large-scale installations using table salt. He recently finished two massive artworks inside an old castle: Floating Garden and Labyrinth. Both pieces are part of Univer'sel, an exhibition inside the walled medieval town of Aigues-Mortes in the Languedoc-Roussillon region of southern France. The event opened two weeks ago and also includes the salt sculptures of Jean-Pierre Formica. Their work will be on view until November 30.
