As home gardeners and farmers alike know, the same plant species can have many different varieties with wildly different looks. Farmers in China have used different varieties of rice to create huge "paintings" in their fields. Rice plants come in many different colors and using those to create 3D art has become a tradition for the farmers in Xibo, where the fields are a part of theme park.
