Japanese artist Motoi Yamamoto sees more uses in salt than the ordinary person. His artwork stems from the death of his sister, who passed away at a young age from brain cancer. In Japanese culture there is an idea of throwing salt over yourself after you attend a funeral acts as a sort of cleansing. So Yamamoto started using salt as his medium, creating intricate labyrinths and mazes as he calls them. Not only does Motoi create intricate patterns but full scale installations as well.
There’s also a beautiful book by Motoi that showcases some of his art called Return to the Sea: Saltworks by Motoi Yamamoto.
