From Simeon Hein: This montage shows various types of electrical anomalies commonly found in and around crop circles. The photo on the left came from a small formation we made in Kansas in 2002. The picture on the lower right shows a camera from last summer damaged by a crop circle at Silbury Hill. And the third image shows total battery failure from the Devil's Den formation in 1999. Here's a link to more crop anomaly pictures.
The second photo is a picture of investigator Colin Andrews with his crop circle damaged camera in the Martinsell formation (right).
