Did all that.

I've tried this before, and noticed that my example only works with spheres.
Any genius out there who can fill a cylinder?

Could use a good LASER macro here, I'll start:
This is NOT visible:

// ************************* WarBird *******************************
#macro laser(A,B,rad,C)
   #local p_id = 0.1;
   #local glow_state = 0.001;  // fader
   #local glow_colorturb = <0.3,0.3,0.3>; //magnitude Randomness to color

   #local ColorJitter =
(<Hash2(p_id,1),Hash2(p_id,2),Hash2(p_id,3)>-<0.5,0.5,0.5>)*glow_colorturb;

   #local Color =
      (
         C
         *(1+ColorJitter) // Randomness to color
         *(1.001-glow_state)    // fader
      );

   #local ColorM = max(Color.x,max(Color.y,Color.z));   // highest RGB
   #local Color = Color/2;

    cylinder { A,B,rad hollow no_shadow
      pigment {rgbf 1}
      finish {ambient 1 diffuse 0}
      interior {
         media {
            emission Color            // color
            intervals 10              // default 10
            ratio 0.9
            samples 4,8       // default 1,1
            variance 1.0/128
            confidence 0.9
            method 2                  //1,2,3adaptive
            density {
               spherical
               density_map {
                  [0.0, rgb 0       ]
                  [0.6, rgb Color   ]
                  [1.0, rgb 2*ColorM]
               }
            }
         }
      }
    }
