Have you tried other patterns? Maybe you should try using ripples or 
waves, or maybe wrinkles. Also, you can use a phase higher than 1 to get 
more cycles.

No...but you can use the same pattern in a pigment as part of an 
isosurface function. This is untested, but should get you started:
#declare WaveFunc =
function {
    pigment {wrinkles phase clock*3
        color_map {
            [0 color Black]
            [1 color White]
        }
    }
}
#declare WaveDepth = 0.3;

isosurface {
    function {sqrt(sqr(x) + sqr(y) + sqr(z)) - 1
        - (WaveFunc(x, y, z)*WaveDepth)
    }
    ...
}
