The spiral may be recursive exemplary par excellence but the circle,
abstracted from its specificity (area) also bends back upon itself.
Octaves "appear" to me as pointillistic powers.
Given the "infinite" divisibility in the 20 to 20k range, wouldn't a 3D
space be a more appropriate abstraction than the circular plane?
