I dont think the portraits in the attic use projection from the front because when I was trying to figure out how it was done, I got a good look into a hole over a picture with light coming out of it. All the light was for was simply to light up the picture and not to project anything onto it. I very highly doubt that it is done from the back. Maybe it is some kind of video screen but it would have to be something really clear. HDTV portrait?
We're going to be there during the makeover this year. Any idea on whether they'll have to take down the new effects for it or will they just try to rework it into the layover?
If memory serves me correctly, everything was taken down in the attic last year for the overlay. I very highly doubt that they will have a singing bride that decapitates her husbands with an axe and a huge glow in the dark snake that eats gifts and a Chritmas list to the tune of Nightmare B4 Christmas in the same room. Sorry, but I dont think it will be there.
