3D Scene from C64 Demo?

I was watching a C64 Demo, and I noticed a particular demo effect. This was a 3D scene where the camera moves forward, and the scene is composed entirely of horizontal lines changed every scanline. Basically a flat vector 2D scene on the Y and Z axis, extruded into to the X axis.

I thought "The NES can totally do that too". I wonder if any kind of game could be made using this style of graphics?
C64 Demo: (this scene starts at 7:40 into the video)

We could make a wolfenstein3d-style raycaster using this, if we were ok with the axis of rotation being the X axis instead of Y axis.

This is actually could be done as a raycaster to allow more freedom on the movements, basically Wolf3D turned 90 degree.
I also had an idea of a low-spec first person Mario done exactly the same way. It would have quite blocky graphics for pipes, but it is certainly possible.

Now there's an interesting idea! Mario should be able to look up and down, so some rotation would be necessary. Pipes could use sprites on the sides to make them more detailed.

The title screen to Gunstar Heroes on the Genesis (and Tongueman's Logic too...) uses the same technique to make flat tilemaps appear to be a 3-D box; other games & demos do it too. Not too computationally-intensive.

I'm guessing the BG layer looks like a solidly colored triangle, and everything is done with raster effects and midscreen palette changes.

Yup, that's the essence of a Yoshi's Island boss.

I remember an Atari 2600 homebrew that did exactly that...

Regarding the original post, it would be nice to see some kind of Rez-ish game ported to the Nintendo that's laid back in game play with beautiful musical accompaniment; which reminds me of "Joomp!" now that I think of it.

Well, there's such a game on the system already if you count the FDS:
