@commanderred@chaos.social It's scanning a drum very fast in front of a high refresh rate led panel. The drum has pinholes arranged in it such that the whole screen gets exposed once per revolution, but at any instant in time there are only a few pinholes in front of the screen. The trick is generate an image on the screen, synchronised with the rotation, which shows the views through the pinholes. The result is that all the light rays of a 3D scene are sent out in all the correct directions.
