I just got these in an email, and I thought it was brilliant! The 'agri-art' is created by farmers in Inakadate in Japan. From what I can see they just use a few varieties, golden, variegated, purple and the plain green leaved (Tsugaru Roman variety).
Apparently the tradition began in 1993, where a simple design of Mount Iwaki was installed every year for 9 years. Then the ideas grew more complicated.
The art covers 15000 square metres of paddy fields.
