Thanks. :-)

I'll attach another I liked while playing. Same set up with complex 
functions, but much lower power exponents. Plus adding in some spiral 
action in the middle.

Another bit I stumbled across working with cf_pow() 'warping' is the 
effective change in scaling from the origin outward makes it pretty easy 
to set up images which change from a near constant color away from the 
origin to something where the f_hash()-ing is clear.

In other words, when the changes in region due the f_hash(), and/or 
higher cf_pow exponents, are happening at >>1 per pixel we end up with 
kind of an aggregate color. As we move to the origin things spread out 
and and we get a fade-in effect. FWIW, I guess, but neat. Hints at a 
possible general technique with on top of f_hash() for fading in or out 
of near constant colors.
