What you can try is to define your neon tubing using Chris Colefax's Spline
include file.  This way, you can make a realistic glass tube (using close
blobs is one way, you get the positions from the "iterated" spline).  Then,
with the lights, if you're game enough:

Define the tube splines.
Loop through the spline gathering points that are close together.
Convert these points into point lights with a VERY dim colour value and
light falloff.

This will create the neon lighting effect you're after.

If you want "glow" around or IN the neon tube then use the same method above
but with predefinded halo spheres (once again these will have to be of a
thin density).


This will of course SLOOOOWWWWWWWW [THUMP!!!!!] Sorry, this will of course
slow down rendering times DRAMATICALLY!!!!!!!!

Just a thought, although I'm sure someone has a better (and faster!!!) idea.
