Here are some pictures showing interesting crop circle effects witnessed by myself or my friends.
1. "Angel -hair" or...? In 1996, Martine Webster was walking across the golf/putting course at Rottingdean, near Brighton, heading towards her camper van which was parked at the top of the hill. She was looking at a bright light in the sky, which had been there for an hour or more. As she looked, the light began to move, and it swooped down towards her. She tried to reach the safety of her friends van fearing abduction, and said nothing to anyone. The next morning, she was told there was a crop circle on the side of the hill, and walked into the field just a few yards from her van, where she found a crop circle with a white, cobweb-like substance in the centre.
The formation was surveyed by SCR, (Southern Circular Research), and reported in SC journal, where news reports are quoted, saying that several people reported lights over the area that night. The formation was a quincunx (=quintuplet) with one of the outer circles missing. Martine knew nothing about the SC write-up, or other witnesses reports until I brought them to her attention over 2 years later.

2. On July 23 1998, a formation appeared next to Silbury Hill, for which The Guardian newspaper later claimed responsibility. However, many of the "grapeshot" circles were swirled into complex standing swirls, the outer ring in this case is swirled anticlockwise, and the inner ring clockwise.

3. At Roundway, near Devizes, on 31st July 1999, a "cosmic sheriff's badge" appeared with a raised ring in the centre.

4th August 1999, this fractal pyramid appeared, with double nested
centre.

4. At Avebury on 29th July 1999, a triangle with 33 circles and 6 superimposed cubes appeared, with some of these tight nests. A week after it appeared, the Daily Mail claimed to have sponsored "Team Satan" to make this formation, but witnesses "Chad & Gwen Deetken were actually by that field until 12.30 am, and Andreas Muller was in the formation surveying it by 5.30 am, the manager of the Henge shop was working by his window overlooking the field on a moonlit night until 2.30 am and the Avebury Social Club, right by the field, had an event which lasted until 2.00 am", Michael Glickman observes in his SC column. Also, the photos of people standing in dark fields, which could have been anywhere, include one of the hoaxers crowded around a diagram of the formation, which was identical to the one which had been pinned up in the Barge Inn, and which, so the rumour has it; went missing, then re-appeared. The newspaper had plenty of time to concoct this story, since it didn't appear for a week, so it could be a hoaxed-hoax, in other words, a genuine formation which had been hi-jacked.

I found several mutated seed-heads in this Avebury formation. Nancy Talbot took some of these back to USA to show to biophysicist W. C. Levengood, and in her presentation at the Glastonbury Symposium this year (2000), Linda Moulton-Howe showed a slide comparing one of these mutated heads with 2 others , (one of which was in barley), found in formations in Canada and USA, also in 1999. Levengood has never seen this effect before!

Linda Moulton-Howe said that, in Levengood's view, whatever caused this, would have to have occurred at least 6 weeks before the samples were found, allowing time for the stems to grow into this shape. So, if this effect is circle-related, (i.e. not caused by pesticides, parasites, etc), then it implies that it is either a residual effect from a previous formation on the same spot, or that some energy was applied to the area at least 6 weeks before the formation, to prepare for it.
5. Not far from Avebury, Wiltshire, a beautiful 6-pointed star and hexagon with radiating circles appeared on July 19th 1999, next to Devil's Den dolmen - a Neolithic structure which is thought to have been a burial chamber originally covered with earth.

Inside the dolmen, there is carved an ancient spiral, linking the site to the spiral lay of crop formations.

6. Between Stanton St. Bernard and All Cannings Wiltshire on 24th June 1999, an "old-style pictogram" appeared. Inside the formation, Nancy Talbot found some classic examples of stretched and bent nodes on the same stems as expulsion cavities. She kindly gave me some of these, which Mel White has photographed for me.

7. On 2nd July 2000, another "Grid formation" appeared, reminiscent of the 1997 Etchilhampton Grid. This one, though, (at West Kennet, Wiltshire), was more complex, with about 1600 components. It is an ingenious fractal of squares within squares, seemingly being four grids of 100 squares each, at the second level of the hierarchy. To me, this represents the 400 Tuns in the last Baktun of the Mayan great Cycle terminating in 2012.

Inside the formation, I found exploded nodes (expulsion cavities) everywhere. Nancy Talbot has verified that they are the real thing. Here are some...
