@foerterer@mastoart.social random displacements wouldn't help here - the holes have to be evenly spaced vertically because that's where the scan lines come from, and they have to be maximally separated horizontally because the closer they are the smaller the addressable region behind them is, and the smaller the angle of view.
If you jitter the holes vertically you get overlapping and gappy scanlines, and if you jitter them horizontally, other than the view thing, it just slightly changes the timing.

@ancientjames@mastodon.social Perhaps I have a misunderstanding about the total number of holes in use and the thing is rotating faster than I think it is? Jittering should allow to get rid of fixed scanlines or a fixed pixel raster in the resulting image, with every projector using its own set of coordinates. Only looking at the y direction, it should reduce aliasing by modifying the view on the panel not to follow the panel’s scanlines but you‘d lose some light since you‘d need to space holes further apart.
