flammarion woodcut is the best way to define OOB, for me. horoscope chart shows condensed/collapsed universe model used by astrologers. essentially one dimensional where circle represents 0° latitude—the equator. using declinations makes the chart multidimensional. operating from an OOB point means sticking your head beyond the veil. there's a sphere here, it's not flat earth... (or whatever). this creates line-of-sight aspects between asteroids & planets; locating asteroid points to draw butterfly of chaos; defining astrological influences by hemisphere &c&c.
