I did a painting incorporating the Star of David, and the Wheel of Life. Both symbols interconnected and painted so all primary colours and their exact opposites, formed the design. The effect when you look at the centre for 60 seconds, is that the colour turns back into light.
A year later I chanced upon a crop circle in Gloucestershire, uk, that represented exactly my painting.
I entered the circle and experienced the mechanism by which it was made. This was a non physical, but visible rod, about a metre in length, that wizzed around the circle parallel to the ground but about 1.5 metres above it. The rod was incandescent, pulsing spectrum colours along its length. One end was pointing toward the centre of the circle, and its movement was pretty rapid, about the speed of a running horse. Over the whole thing the light had an apricot coloured hue.
I saw only just that part when my gaze shifted into timeless time. I conjecture, the rod wizzed around at ground level too, and all subsequent levels above, to make up to the top of the hemisphere of apricot coloured light. I had the clear impression, the crop circles are three dimensional, and can be viewed as such. It would be amazing to use computer imaging to create them as 3D objects.
