About halfway down the descent, if you look up and to the left (about a minute after you see the spaceship, give or take), you can see one of the old dioramas from the 94 version that they never removed. This one depicts a row of people with a couple of them wearing graduation caps. It looks almost like a plywood cutout that was painted black. Supposedly many of the dioramas are still there, just hidden in the dark. I saw a few other cool things, like areas in the walls that were set in a few feet where scenes used to be, but this was the only actual diorama that I could spot. This was the first time I didn’t play the build your own future game so I could sit back and look for remnants, and it was WELL worth it. Very cool stuff.
