The fantastic pipe organ from Pirates of the Caribbean: Dead Man's Chest
Ludicrously hard to take a photo of without a tripod, and I'm still not sure I'm entirely happy with the outcome. The prop is flatly grey, and they've got it all set up with these colored lights to bring out the look from the movie, and it pretty much angered my camera.
Disclaimer: I didn't build Disney World.
I just took the photos.
Still...they're my photos, so please don't do anything involving selling them or taking credit for them.
