I've read many of the posts in the past about the 
pros/cons of framing, but I've come up with an 
idea for displaying a cel that would require some 
rather unique considerations in framing.  The 
first thing to note here is that the cel that I 
would be framing would only be one bought 
specifically for the purposes of this project and 
wouldn't be of much value except that it fits in 
with what I'm doing.  Not going to give too many 
details on that now, but here's the basics on 
which I could use some advice:

a. I'd like to make a frame out of plexiglas, the 
thinner the better, which would allow visibility 
all the way through (ie: plexiglas in front & 
back, exploiting the transparent property of cels)

b. I'd like to display this with lighting coming 
from behind -- I know sunlight is a very, very 
bad thing, but does anyone know the relative 
dangers of things like led's, cold cathodes, or 
neon lighting? (or if there's any factors 
depending on the coloration of said lighting?)  
Keep in mind that the primary light source would 
be coming from _behind_ the cel, not the front, 
so it might be more of an issue of what it would 
do to paint rather than line fading.

Sorry if this is really vague, but I don't really 
want to let the cat out of the bag too soon, 
since I'm not sure how long this will take to 
finish (might hear about it again in a few 
months).
