Disney projects over Elsa for her wardrobe change on the DCL version of the show. Disney seems to keep working on this projection mapping technology with every change they get.Didn't know they were already testing Fantasmic 2.0, but it seems like they are already teasing some of the additions. Projecting over moving objects can be quite tricky. I think Intel has been playing with that for a while. Hopefully they'll make it work.
And I'm sure people will miss the original show, but I'm usually very open minded about things changing and evolving.
