It gives the wish to go inside the image to wander in the garden. I'd like so much to understand all that is behind the mandelbulbs and how to explore them. It's really amazing.
Thanks - in case you're wondering the colouring is simply the smooth iteration value - it works because "solid" is entirely based on the distance estimate threshold (i.e. the max. iter. is set so high that it's never reached) hence the 3D outline of smooth iteration does not match the 3D outline of the object.
