Years ago at Disneyland our company took us there to spend the day for a Christmas holiday gift to us. The owners were very friendly with a long-time Disney executive who accompanied us while we were there. After we were done at the Haunted Mansion he was going to explain how the holographic images were made and I excused myself and stepped away from the group. I explained before I stepped away that I'd just rather not know the mechanics of it. Have you ever done anything like that?
