It's worth adding that the scanned resolution is independent of the resolution of the LED panel. The approach is essentially the same as a mechanical TV, where the disk (or drum) is scanning in front of a single light source.
The resolution is limited by the number of holes vertically, and how many times it can change the light intensity during the horizontal sweep of the hole. (As it turns out, here the scanned resolution is 80x48, basically the same as the panel's 64x64)

The other neat thing about this compared to a 2D mechanical TV is that the view window is much larger. With a single light source there can be only one hole illuminated at a time, so with 36 lines you can only have a window 10 degrees across. This doesn't have that restriction - it can have multiple holes in front of the panel simultaneously as long as it's rendering a separate view to each hole's local region. In fact, the plan is to add more panels and make it fully 360.

@ancientjames@mastodon.social Ah, wow. So the holes do not necessarily all have to be circular?
