The question of why a pentagon is inverted in the centre of an upright pentagram (5-pointed star) in the Riesi, Italy crop circle is at least partially answered by interpenetrating with four stars in alternating positions.  The position of the star “standing” on two points or one point is commonly used to represent “positive” or “negative” orientation, which can be viewed as straight-forward polarities.  A diagram of four stars shows how alternating “up” and “down” positions results in an inverted pentagon at the centre, when points of the fourth star are connected with lines and completely filled.  I also did a diagram showing location of the three crop circles reported in Italy during May 2012 on the Time Star.  The crop circles are positioned on the tetrahedron associated with Africa and aligned with a new island that is forming at El Hierro in the Canary Islands.
