I see the pips are following the golden spiral in Fibonacci numbers, but i have no idea why is it being used in here? I may be wrong, but Fibonacci numbers are used in mathematics, which would seem quite different from an "artsy" painting deck. The closest relation i can get to it is the usage of the golden ratio, which i believe in some form of arts, uses this theory.
I'm just asking simply because for a layman, the pips seem very irregularly placed if they have no idea of what Fibonacci numbers are. These plus a sequence with no relation to painting on water, which i imagine to be fluid and irregular, and definitely "non-golden ratio".
