The GM pavilion was by far the most interesting thing at the fair that year...at least to a 16 year old kid (and I'm including the roller coaster). Sadly the footage isn't the best, but the quality of the projection was excellent. The show was an old native American telling stories that came to life in his campfire smoke. It wasn't until the end that he becomes smoke and you realize he wasn't an actor, but was also a projection the entire time. It was amazing, and more than a bit sad that we don't have holographic movies today, seeing as it was clearly possible 30 years ago.
I don't remember much of the rest of the fair. Lots of silly movies and miniatures, a few performances, a couple of rides, and lots of oddly depressing foods. GM definitely won my vote for best exhibit by far.

Actually, that video is good quality for a home recording! Hey, post the other parts. Good flashbacks. My folks, grandqueens, church friends, and I were there too!!

Part 2-

As was I, at 16 as well. I've got too many photos of the Micro-Tokyo model.

Is that the outdoor mascot robot?

?!?
Jump to 1:15 to see the micro-Tokyo model.

Oh that. I think I saw that in person too. What was the name of that robot moving around outdoor?

I don't remember it, it must not have made much of an impression.
Google/Wiki says he was Expo Ernie. Was he rolling around the fair, just in commercials, or what?

That was him! Dude, he was big and popular outdoor. I totally loved him.

Odd. I have no memory of him at all. Perhaps I just somehow missed him the whole time I was there.
Did he talk, just wave his arms, roll around, or what? Was it just a guy in a robot suit, or a real robot, or a remotely controlled fake robot, or what?

I don't remember. I just remember him moving around slowly, taking pictures with humans, etc. I don't remember him talking. Maybe he did. Maybe someone else would know? I couldn't find anything online about the details.

Moving this video to newtboy's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.
