A lot of demo effects are almost like magic tricks --- before you understand how they're done, they seem like impossible magic; but once you do, you think "that's so simple, why didn't I think of that?"

Animation by essentially "panning" inside a larger pre-rendered image is one of those tricks:

Old-school demos have another common trait with magic. Like the best stage magic, you know you are being fooled - but even after seeing how the trick is done, you remain amazed by it.

The best one I have seen: Cubase-64 [0]

I'm not so sure how simple the example you mentioned is. I've seen it many times and I'm still not sure how I would generate the source image.

Hand animated cartoons would often used that trick as well.

The anime Bubblegum Crisis used a massive cityscape painting for their panning shots.
