These displays use rotating mechanisms.

This ones does not: https://www.youtube.com/watch?v=wrfBjRp61iY

Volumetric display in the video above uses static projector whose pixels light up etchings inside solid glass.

feel like I saw this in a hackaday, at least remember hearing the podcast about projecting all the rays at all intersections, it was green though maybe I'm thinking of something else

oh wow yeah I've seen a lot of this channel's work before the lego display, the CV fiber optic bundle display
