I don't know about bringing cels.  I had mentioned
possiblility of doing a cel panel several months
ago if could find a co-host but never heard back
from AWA guys after they expressed interested.  I
think Melissa from Junk Jungle has been in more
recent contact with them to know what is going 
on.  

You could always bring a celbook for people to 
look through, but since panel is only for an 
hour - depending on the number of people may not 
be possible to look at everyone's cels.  I 
probably will bring a small amount of cels.  If 
no one else offers, I am sharing room in main 
hotel with 3 other people - so could store 
celbook if can find me.  I don't know which 
costume I will be in, except it won't be Zelgadis
(don't wanta leave blue smears on people/cels.)
