These are just some more patterns I found while playing with functions. 
They use the Isofunctions.inc file I uploaded to 
povray.binaries.scene-files.
They all use a plain black-white color_map and have an ambient of 1.

The big sphere on the left:
function {Noise2(Phi(x,y,z)*15,0.5,sin(Theta(x,y,z)*16*pi))}

The upper right sphere:
function {
    (Noise2(x,y,z)
    +Noise2(x*5,y*5,z*5)
    +Noise2(x*10,y*10,z*10)
    +(Noise2(x*20,y*20,z*20)^0.3))/4
}

The lower right sphere:
function {
    (Noise1(x,y,z)^0.3)
    *Noise1(x*5,y*5,z*5)
    *(Noise1(x*20,y*20,z*20)^0.3)
}
