The designs below are just a small sample of some of the designs I have found.
A portion of the Mandlebrot set located at -4.11999e-03, -8.270512500e-1, extending for 1.123199e-2, 8.985599e-3 using 128 iterations.
This illustrates a similar general design to the 'Treble Julia set' crop formation discovered at Avebury Trusloe in 1996.
Another easily recognisable fractal shape appeared just behind Silbury Hill, Wiltshire in 1997. This time it is the 'Koch' curve.
