While I love and adore the original Haunted Mansion more then words could ever tell, I also think that this incredible new technology would be pretty impressive if utilized in the Haunted Mansion ballroom scene. Just think of how incredible it could be if utilized properly.
Check out this video of the technology from the company Musion and imagine how incredible it could be if used correctly. I guarantee you this will blow your socks off!

it gets pretty awesome at around 1:25, there is one or two bad words at the very end I just heard though so be careful. PG-13 (for language) actually it would probably be PG since it is only 1 bad word.
