A nautilus shell forming the Fibonacci spiral, labeled with the numbers 21, 13, 8, ringed by botanical elements. The foundational image of Woven Number Theory — the sequence that builds itself from a single recursive gesture. The same spiral that appears in the PolyScope, in the King's Chamber measurements, in the digital root cycle of FIBO60.
