Lets face it: star constellations – and hence zodiacs – are an entirely arbitrary human choice. There are neither 12, nor 13 zodiacs, there is an almost infinite number of visible stars in the sky, from which a literally infinite number of “constellations” can be generated by connecting stars with lines. Not the sky, your phantasy is the limit. You can also divide the year in arbitrarily small intervals (say: picoseconds) and define your own zodiac depending on where planet Earth happens to be on its orbit with respect to the stars at that picosecond.
Lets take a look at Taurus (which they tell me I “am”):

Or in a more sober representation:

And here is what the night sky around there actually looks like:

Oooooh WOW! I can totally see a bull here! If I consume a lot of fungus. So now lets forget about all the zodiastic taurusshit and reveal my REAL zodiac (25th of April 1977, 6am, 320e+12 picoseconds):

Surprise: my zodiac is Unicorn! As can be clearly seen, Elnath defines the tip of the horn, while Aldebaran makes for the shiny ass. The anomalistic year (time between perihelion passages of the Earth) has an average duration of 365.259636 days, which amounts to 3.15584325504e+19 picoseconds (=number of distinct zodiacs in our system). We therefor randomly assign number 2.504197706e+12 to this zodiac. I think it’s a good zodiac. Character traits associated with “Unicorn” are: sexy, a bit vain but kind, icecream. The picosecond division of the year also means: not many people have it!

What is your zodiac?
