I was a bit inspired by Episode II, so here's a quick model I did the other
night..It's supposed to look like Yodas saber, which I found some pictures
of on the net.
I got the media ideas for the blade by looking at a scene file (sabre.pov by
Kenyon Banks) I found in the newsgroups.
So far all the sabers are the same..likely to change if I get the time. The
background is some hubble picture I came across..

Glad you like it!

> how did u do the blade?
One small cylinder in the middle filled with media (I_Blade2) and a large
cylinder also with media (I_Blade).
I'm not satified with it yet..I'd like the places where the lightsabers
cross to bercome white, not a blend of the two colors. But I haven't used
media much, so I don't have a clue on how to achive that.. something to do
with absorption?

Here's the messy code:

#declare Sta = 0.5; // just for testing
#declare CLR = <0.25,1,0.25>; // color
    #declare I_Blade = media {
      intervals 10           // number of intervals used for sampling [10]
      samples 1,1            // minimum and maximum number of samples taken
per interval [1,1]
      confidence 0.9         // statistic parameter higher->better quality
[0.9]
      variance 1.0/128       // statistic parameter lower->better quality
[1.0/128]
      ratio 0.9              // distribution between lit and unlit areas
[0.9]
      emission 0.3           // emitting media, emit light of specified
color
      method 3               // adaptive sampling
      density {
            cylindrical
            turbulence 0.05
            color_map{
            [0 rgb CLR transmit 1]
            [1 rgb CLR transmit 0.8]
            }
      }
    }
    #declare I_Blade2 = media {
      intervals 10           // number of intervals used for sampling [10]
      samples 1,1            // minimum and maximum number of samples taken
per interval [1,1]
      confidence 0.9         // statistic parameter higher->better quality
[0.9]
      variance 1.0/128       // statistic parameter lower->better quality
[1.0/128]
      ratio 0.9              // distribution between lit and unlit areas
[0.9]
      emission 0.5          // emitting media, emit light of specified color
      method 3               // adaptive sampling
      density {
            cylindrical
            turbulence 0.05
            color_map{
            [0 rgb CLR transmit 1]
            [1 rgb CLR transmit 0.8]
            }
      }
    }
    #declare Beam =
    union{
        merge{
            cylinder {-y*1,y*70,1.8-Sta}
            sphere {0,1.8-Sta scale <1,1.5,1> translate y*70}
            interior{media{I_Blade}}
            pigment {rgb CLR transmit 0.9-0.3+Sta }
            finish {ambient 0.2}
            hollow
        }
        merge{
            cylinder {-y*1,y*70,0.5}
            sphere {0,0.5 scale <1,1.5,1> translate y*70}
            interior{media{I_Blade2}}
            pigment {rgb CLR transmit 0.9}
            finish {ambient 0.9}
            hollow
        }
    }
    object {Beam translate y*20.1}

transmit doesn't do a thing in media.  You should use:
color_map {
    [0 rgb CLR*0]
    [1 rgb CLR*.2]
}

Wanna bet?  Try setting transmit to 1.5 or something...;)

Must be a POV-Ray 3.5 thing then, cause it doesn't do anything in MegaPov
0.7
