1. A huge complex design appearing in a short time

People can accomplish a lot even in a few hours, but there are some realistic limits. Lets look at some good examples in Wiltshire, England.

Stonehenge 1996; some 150 circles appearing in a time frame of max 45 minutes in clear day-light

West Stowell 1998; a huge 7-folded ring shape, including 175 extremely delicately laid-down small circles, during the dark night hours

Bishop Cannings, 1999; stunning "basket-woven" design in a 29-circle star pattern, one night

East Kennett, 2000; 1600 squares within a very large circle, again during one night

Woodborough Hill, 2000; a large torus shape made of hundreds of triangles, in one night

Milk Hill, 2001; over 400 circles very neatly laid-down overnight in one of the largest Crop Circles ever
