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.

In general, hobby photo-lithography projects already use DMD/DLP projectors, and some inexpensive optics.

In general, getting vanity silicon made is usually much less expensive than trying to bootstrap a fab line. =3

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...).

This might be relevant for Augmented Reality headgear.

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.

It certainly looks like something that will find novel applications.

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

Cool. Now I can show videos to my fruit flies! /s
Srsly title should be "MEMS Array Chip the Size of a Grain of Sand Can Project Video"
not
"MEMS Array Chip Can Project Video the Size of a Grain of Sand"

It is actually about a 0.125mm projection, not the size of the chip. But more about steering lasers, which is really what they wanted to do.
