First ten digits of Pi encoded in crop circle

This 50 meter wide crop circle has recently been spotted in a barley field near Barbury Castle, Wiltshire, UK. It depicts the mathematical constant Pi to ten significant figures.

Overlay made by reader Steve McMath:

The tenth digit has been correctly rounded up. The little dot near the centre is the decimal point. The code is based on ten angular segments, with the radial jumps being the indicator of each segment: Take the pattern and draw radial lines from the center of the central depression through each radial jump. Take the smallest angle sector and call it one (1), then compare the other ten sectors contained angle to the smallest and pick the closest single digit for the ratio. They come out as 3.141592654.

Another circle with a message

The disk reads (encoded in ASCII): “Beware the bearers of FALSE gifts & their BROKEN PROMISES. Much PAIN but still time. [Damaged Word]. There is GOOD out there.We OPpose DECEPTION. Conduit CLOSING (BELL SOUND)”

Aliens read Slashdot

Here is how to make your own crop circle, but some argue that the “real” crop circles are far to perfect to have been made by humans.
