Move over, crop circles
"An enlarged work by Aomori woodblock artist Shiko Munakata (1903-1975), stands out in a rice paddy in Inakadate, Aomori Prefecture. The work was created by a local village promotion council, commemorating the 100th anniversary of Munakata's birth. Underneath the reproduction of the work are the words, "Inakadate, a village of rice plant culture." About 600 people in the village planted purple, yellow and green rice plants, which formed a picture as they grew."
