Very nice! Did you use some orbit traps for colouring?

It's using a point trap centred on the origin for ambient occlusion lighting (i.e. using the adjusted trap min dist to scale the ambient amount in the standard Phong model).
The colours are from the smooth iteration value: solid is based purely on distance estimator threshold so the smooth iteration contours are different from the solid outline which results in the useful colouring method - in actual fact appropriate adjustment of the smooth iteration value using this method can result in a colouring that's almost identical to what you get from min dist point orbit trapping at the origin

Thanks for explanation. I have to make some trials with point traps. Now unfortunately I have the FLU (but fortunately not AH1N1) now and I don't have enough strength for thinking.
