I wonder if this has implications for custom home chips/prototyping. I'm sure a big issue is vibrations but something like this could remove the need for masks at least. (again, not my area so I am clobbering terminology I am sure). It may open up home fab capabilities.

This reminds me of the original patents that Magic Leap had, which involved pumping light through a single optical fiber that was wiggled by piezoelectrics into a spiral to project light (https://kguttag.com/2018/01/06/magic-leap-fiber-scanning-dis...).

Sounds like this will have interesting fiber-optic implications?

This might be relevant for Augmented Reality headgear.

What is this, a movie theater for ants?

This may seem small (barely visible as a dot to the naked eye), but that's also the geometric mean of the Planck length and the diameter of the observable universe. So average size actually.

How do you even fit a video projector onto something that small, the physics feel like they shouldn't cooperate.

This is actually getting close enough to manipulate the _phase_ of light! And doing that would allow creating true holograms.

Or alternative true augmented reality glasses that are not limited to one focal plane.

Oh wait. It does have the correct title. My fruit flies are cheering.
