This thread concerns the premade insert menu files. The one Bob is pointing
out comes from the insert menu for the blob object. In particular he is
refering to the way the radius and blob strength is defined for that object
as follows:

// create a smooth blobby shape
#declare StrengthVal = 1.0 // (+ or -) strength of component's radiating density
#declare RadiusVal   = 1.0 // (0 < RadiusVal) outer sphere of influence on other      
                     // components
blob
{
  // threshold (0.0 < threshold <= StrengthVal) surface falloff threshold #
  threshold 0.6
  sphere { < 0.75,   0,    0>, StrengthVal, RadiusVal }
  sphere { <-0.375,  0.65, 0>, StrengthVal, RadiusVal }
  sphere { <-0.375, -0.65, 0>, StrengthVal, RadiusVal }
  cylinder { -z, +z, 0.1, StrengthVal, RadiusVal }
  // [sturm]
  scale 2
}
