I highly doubt the radok screens will ever come back...however....that doesn't mean an interesting preshow can be done in different colors and patterns on the 5 flat projection screens. We need a better, more fluid preshow explaining all the different sources of energy....not a dry....bland graphics presentation......the original preshow was quite dry in narration...its graphics weren't stellar....and it was only good due to the radok screens.
The theater 1 film could possibly use the original animated film made for the UoE which would remain timeless...or a cutting edge graphic presentation about the major use of energy...fossil fuels....though the graphics may become outdated within a few years
I would love to see the Radok screens come back, I have a feeling that technology has improved enough that it would make them reasonable to maintain. And they would be mind-blowing with the right presentation.
The one thing that I think should be retained that has come out of Ellen's Energy Adventure is the Big Bang sequence. Expanded to fill most of the Theater 1 movie, with modern graphics and rendering, and without Bill Nye and Ellen, of course. It puts the Universe in "Universe of Energy"
Two words, John Williams!
Nah, I have him in mind for either Spaceship Earth or Horizons.
