A virtual CRT simulator, emulating the various attributes of CRT displays. Shadow masks/aperture grilles, phosphor glow, bloom, geometric distortions. EmuVR does some of this already but it'd be a fun novelty to have such a thing in a AR headset with Vision Pro's resolution and other capabilities.

The lack of a 60/120hz mode will cause inevitable stutter, but that's going to be the case with any 60hz content (24p will be fine due to the 96hz mode).
