Prop cam compressed motion picture effect idea

I don't have a prop cam but do have other image sensors that I have been thinking of trying this idea with for a few years.
The idea for the effect has limited use, specifically perhaps for creating a compressed point of view of the camera if it is
attached to the front of a vehicle that is moving at a constant speed. It should be virtually possible to compress each frame
Into one line of bitmap as long as the camera is moving forward in a straight line.
The idea is like cosmic zoom effect. Each line saved would actually only be a straightened out circle of pixels that just fits in the
image taken of each frame. On playback, smaller circles from the future frames would be drawn inside the largest circle,
And parts of past larger circles may be drawn outside of the large circle. The video file made can be thought of as a very big
slinky spring that you are flying through, painted by the pixels taken only from the large circle during each original frame.
I imagine that anything else in motion being recorded this way will be distorted in weird ways, and weird distortions would
happen if you turned while recording. It is similar to taking a picture with a flatbed scanner also called slit photography,
Since space (z axis) and time are sharing the same dimension in the data.
I expect that the math for placing concentric circles would involve some adjusting non linearly for distance,
And I think that square roots involving the Pythagorean theorem might be simpler than sine and cosines
For placing the pixels of concentric circles that the image consists of.
I'm just putting this out there in case anyone might be interested in trying it.
It might be fun to create a "world" exploration game out of many "slinky movie files" stored on an SD card,
recorded the way I tried to explain, in some enchanting place.
A single slinky video might also be made by moving in a large circle that begins where it ends and repeats,
and have the effect of flying around some place.
The slinky video file(s) could probably be further compressed by recording the helical bitmap as run lengths of same gray levels.
I got the idea by trying to guess how this was made:
