I knocked this together at lunch time. It's not supposed to look like this, but
some interesting errors occured in the media formula! I particularly like the
line of ufos that appeared in the first image, I didn't put them there!!

I found that I could remove these "errors" by reducing the size of the object
the media is in and increasing the samples, but I thought I'd post the error
'cause it looks much nicer than the proper version!

For those who are curious, the media density looks like this:
    density {
     function {
      1/(0.001 + sqrt(x*x + z*z)*y)
     }
     scale 1000
     translate -10*y

     poly_wave 3

     colour_map {
      [0 rgb 0]
      [1000 rgb 10]
     }
    }

Though the formula was a bit different for the first image.

Do you like it?
