Originally, I had thought about using 3-D to create a DisneyQuest-style simulator for extinct attractions. Another possible space for this type of an attraction is StarTours.
But it occurred to me, especially if Tomorrowland were reimagined as a themepark/DTD of the future, HISTA would be great as Tomorrowland 2055's preview center for Tomorrowland 2065. Do like Disneyland did for Pirates in the Tencennial show. You could do a fun show with behind-the-scenes footage of the Imagineers working on the design, take us on a virtual tour of the exterior and queue, and then have the "ride-through."
