I'd take one of the two OmniSphere screens from Horizons (along with a projector of course), and a Star Tours/Body Wars ride vehicle. Hook your video game system into the screen and find a way to rig the interior lights and strobes to react.
My day job is with a former Epcot pavilion sponsor. When that sponsorship ended, my friends and I called every high-ranking person we knew in our company, trying to get one of the pavilions signs with our company logo on it. I would have then, and still would now, pay a lot of money for one of those signs.
The Alien Figure
XS Teleportation Tube
AE Entrance Sign
S.I.R.
Skippy
Or anything else that was in that building from 1995-2003
Now the non obvious ones:
Horizons panel that had the endings to chose
The Figment that hitchhikes a ride to the moon (Always my favorite)
Old Tower of Terror Lap Bar
The AA from World of Motion that was looking up from the sewer in the city scene
A Pair of 3D glasses from Captain EO
I like the tram idea - I want one too. I just want to say I own a vehicle that defies the laws of physics, where each successive axle follows the one in front of it - NOT POSSIBLE! :lol:
I'd like a Splash Log, and a Steam Train, and my very own Stretch Room, and a ToT Elevator - spooky!
The funny thing is, about half of the items mentioned here either have been, are or will be listed on Ebay. So much is available, some for reasonable (relatively) prices.
I'll keep my eyes open for a doombuggy vehicle, tiki room figures (birds or flowers, or even tiki's), a tile from SE, this can be a very long list...
