I observe: 
1. tan areas which are stable			@B++ increases
2. yellow crud in tan areas
3. swirls
3. purple stuck-on vortex centers

A. Swiss Cheese		@A++
B. 1D symmetry
C. stabel bands
D. constant velocity sweeping bands -- one natural F

1. some areas will support ongoing oscillation, but will not start oscillation.

Enhancements:
symmetry breakers
Ranomize puts blocks there (a standard swirl)
Speed slider.
Finer Adjustments (perhaps hysterisis)
