A mysterious crop circle with this evocative design of a nine pointed star appeared on 7/18/1999 near Cherhill, in Wiltshire, England. It is a traditional Masonic star, and composed of three overlaid triangles. It is also used in the field of Neuro-linguistic programming and is called an Enneagram, representing nine distinct personality types and their interrelationships, mapped around an ancient symbol of perpetual motion.
