This second image shows a simpler f_hash of x; combined with a seven 
entry color_map and two warps.

Herein also playing with ideas for another run at a f_spiral() 
replacement function - given the existing one has some awkward 'quirks.'

Start with an increasing rotation moving toward the center. About a two 
thirds of the way into the rotation, blending in an increasing 
displacement directly toward the center. This gradually turns turns the 
rotation into a more traditional spiral. Thought is to do something 
similar for a 'f_spiral()' replacement. We'll see.
