In the 1970s, crop circles started appearing mysteriously all over the countryside of England, and people attributed the bizarre compressions in the earth to flying saucers and unseen forces in the environment. In 1991, Doug Bower and Dave Chorley confessed that they were behind the crop circles, but by that time, the public was already hooked on the mythology of the designs in the earth. Today British fields are still home to some of the most impressive crop circles in the world, especially in the Wiltshire region. Also, large-scale designs in cornfields have cropped up in the German countryside as well as other places in Europe. In 2002, M. Night Shyamalan's movie Signs again brought the crop circle into the public sphere, and the world has shown a continued fascination with the enormous beautiful patterns. People who create crop circles have come up with some elaborate designs and precise patterns, and the result is something akin to Earthwork and Land art or temporary outdoor sculptures. Created by aliens or artists, here's 30 Awesome Crop Circles.
