I’m thinking of this one. Specifically, the part I skipped to where it looks like going down a tunnel of time.
How did they create that effect in the mid-1970’s?
Here is a nice link of all the openings, if you are curious.
Oh, I guess it is called slit-scan technology? How does that work exactly?
You could create that effect with video feedback.
In fact it appears that’s exactly what they did, then they went to the slit-scan method.
