Thanks Chris. I haven't been to clear on the whole issue of translating
glows. Your statement confused me, so I did some trial and error tests. It
seems that, as you stated, you can translate the glow itself, such as:

light_source{<0, 0, 0> color rgb 0.045
 glow {size 0.4 type 0 translate 10*y }
 fade_distance 4 fade_power 2}

But you can't do:

light_source{<0, 0, 0> color rgb 0.045
 glow {size 0.4 type 0}
 fade_distance 4 fade_power 2 translate 10*y}

Is this correct? If so, that's going to be the problem with this scene.
Remco created the tree by creating the branches and ornaments one at a time,
then translating them into the proper position. The original idea, of
course, was to add the lights to the branches along with the ornaments, but
this won't work given the way that the things are.

Is anyone else as confused as I am? Is the glow is an attribute of the light
source object, not an object itself? How can you specify the location of the
light source and not be able to translate it? And why can you translate the
glow if it's an attribute? Ouch, my brain just siezed up!
