I chose the circle because it contains both Pi and Phi, which are significant Fibonacci numbers, and represent phases of a cycle. The geometric shape of a circle bests represents a cycle completion, and we are (hypothetically) approaching what could be the completion of the current cycle. The circle contains 360 degrees. If we divide the circle into 6, 60 degree radians, we end up with each radian roughly equaling Phi. This is why I found 6 cycle phases interesting, which were are seeing now.
Currently, I have no idea what the significance of this means, and I will continue to research, as I feel that I am close to something significant. I will post more findings as they come to me. Enjoy.
