* From wave form pictures: nothing looks really special apart from
low-denominator rational numbers.
* From analysis: it's clear why for low-denominator rational numbers
there is no low-frequency content, and why there is some LF content
for high-denominator rational numbers, but not (yet) clear that this
follows the frequency slope from linear analysis (== inverse of
integrator == high pass noise).
* The non-leaky 1st order accumulator is really a value -> frequency
converter. It has non-vanishing autocorrelation. From this another
suggestion for decorrelation can be suggested: integrator state
increments/decrements with average 0.
