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...).
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.
> The chip projected a roughly 125-micrometer image of the Mona Lisa.
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.

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"
