"Visualizing the Riemann zeta function and analytic
continuation"
(Watch the last 30s or so if nothing else. You'll not regret it.)
There is a kind of 'real' Ural spiral [or really a kind of chaotically decaying 'orbit'] related dynamic that gives the prime numbers (assuming the RH.)
Conceivable that OP's pattern might have some relation to this dynamic, and fun pondering to boot.
