No, that's not what I'm doing. Of course, scaling along the 'y' axis gives
expected results, in changing the roundedness of the end cap.  Examples of the
correct, expected behavior in the code below and the attached image...

blob{
        threshold 0.4
        cylinder {<0,0,0>,<0,10,0> ,0.25,1    scale <1,0.1,1>}
        pigment{Red}
        finish{IsoFinish}
        translate <-1,0.0,0>
        }

blob{
        threshold 0.4
        cylinder {<0,0,0>,<0,.1,0>,   0.25,1 scale <1,10,1>}
        pigment{Green}
        finish{IsoFinish}
        translate <0,0.0,0>
        }


blob{
        threshold 0.4
        cylinder {<0,0,0>,<0,1,0>,   0.25,1 scale 1}
        pigment{Green}
        finish{IsoFinish}
        translate <1,0.0,0>
        }

I scaled the x &  z dimensions of the blob component and get a wacky alteration
of the blob in the y!! This is not mathematically correct, IFMSS. Look at the
code in my original post here....
