Like the imaginary map drawing exercise, doodles generally allow the necessary degrees of freedom for creative self-expression and the unconscious projection of astrological natal chart parallels. Tokens of birth planet positions can be found mimicking the placements of Moon and Mars, for example, as is the case with Helen Mirren's doodle:
There is a little angular distortion introduced by the way conventional charts have dealt with how to place to tenth house cusp according to season and latitude, but we can see Mirren's Moon ar the top of the chart, and Mars on the left, above the horizon. These two points allow us to see that the doodle agrees with the birth time placements of both Moon and Mars:
Here the prominent Moon is projected in the guise of a large crescent shaped feather at the top of the doodle, and Mars is indicated by the sharp finger tips. I think I like these instances of Horoscopic Expressionism the best; they seem so spontaneous and naturally occurring.
