The original incarnation of the attraction was indeed the best. I'm sure a quick Google search will find illustrations of that attraction's interior.
IIRC, there were elaborate scenes with vivid colors depicting different parts of one's imagination. A room of words, for example, depicted the meanings of some words visually. The word "earthquake" would be a big, shaking sign with a crack down its middle. I always thought of it as a visual onomotopaeia, but that might be not an entirely accurate term.
Other rooms involved colors, storytelling and unusual scenery. I recall an entire upside-down kitchen - built to almost scale - suspended from the ceiling. It was quite the clever attraction.
The original attraction also had a number of (for the time) pretty cool interactive features. How many of us jumped on those colored lights to make different sound effects? Who didn't love conducting an electronic orchestra by waving your hands just so? How many times did we run our hands under that table with all the machined pins? Ah, those were the days.
I've heard rumors that Kodak is soon to depart Epcot due to its (Kodak's) financial situation. If you've got the time to look up the term "PhotoPass" on the U.S. Trademark Office's website, you'll find something interesting.
Thanks for the memories.
