Japanese rice art, from a listserv of which my friend is a member:
"Stunning crop art has sprung up across rice fields in Japan , but this is no alien creation. The designs have been cleverly planted. Farmers creating the huge displays use no ink or dye. Instead, different color rice plants have been precisely and strategically arranged and grown in the paddy fields. As summer progresses and the plants shoot up, the detailed artwork begins to emerge."
