I am typing Out loud as well! (and by the way...it's nice to be on the team with all of you!)
I have been thinking that... so far...each pavillion kind of covers (or once covered) a different Science.
I have been trying to think about this as well...
There is Space travel in Mission Space...(but not really Astronomy...or planetary sciences)
Earth Sciences are the Land, Living Seas, and I suppose Geology is taken care of in Energy...(though the fun aspects of geology...like gemstones isn't part of it)
Kinetic Energy and transportation used to be in World Of Motion, and now in Test Track,
and Wonders of Life was Biology...and Horizons took care of futuristic domestic/environmental projections.
Imagination used to cover the other side of the brain/human condition....
Though there isn't really a philosophy pavillion
History is sort of covered in Spaceship Earth...as the history of comunication...
So...what about a Money/Financial idea? The history of what is wealth, what is valuable from gold to gems to paper money and how it's made...
Which also makes me think of Technology of Detection...spy stuff, or futuristic police detective CSI type stuff...which has a great scientific base, but is also kind of fun...
There is also Media...or the future thereof...discussing micro technology and how it continues to affect music, movies, and other forms of media blended with science.
And then there's the idea of doing another kind of Horizons...hopeful projections about the future of humanity...but taking a different route than the previous one...and projecting...I dunno...some other sorts of things that will affect the human condition (rather than where we might live)
Wow...when i think about it...there's a whole lot of cool stuff that would make a totally kick-______ pavillion, and still retain the wonder of Epcot's vision.
Allright...sleep now. (And no, I don't want to be the leader!...
)
