I don't really know if this is a good idea:
When I once was thinking about about how to create real random cloud-shapes,
I got the Idea that it may be possible to use D-Noise to create some
Random - shapes That may look like bubbles or clouds or something like that.
A possible Parameter may be a Float-Value between 0 and 1 which is defined
to be inside the single shape, which means that the surface is exactly  that
value.
This shape will need some other shape to Bound it.
A D-Noise cloud-shape-call might look like this:

DNoise_obj{
            surfaceValue 0.3
            texture{
                    pigment{ color {rgbf <1,1,1,0.5>}
                                    }
                    }
            scale 10
}
