There is a deeper identity beyond Sun signs, and I figure that you can 'calculate' the elements combining in your soul womb - i.e. one must take one's Moon and Sun signs and figure out what they mean. Now of course there are 4 elements, 12 signs, and so 3 of each (3x4=12). Water and Fire; Air and Earth; but each sign is its own essence, in its family of elements: and once one figures this as a Sun-Moon pot, one can determine one's sub-elemental goo as I like to call it.
There are 144 distinct Sun-Moon combinations. These can be further categorized into water-fire, air-fire, earth-water, etc groupings, as well as mutable-mutable, etc groupings. Each of these groupings form a subelemental goo which are more specific than saying "I'm a Virgo" or "I'm a fire sign": if we presume a Gemini Sun and a Libra Moon for instance was a specific element which formed its own identity, and might call it a Geminibra or somesuch, or assign it a specific color, say vermilion, then we might counterpose this new expanded form of astrological identification to undermine the general state of pop astrology as being surface level and based on Sun signs.
