    > 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.

    This might be relevant for Augmented Reality headgear.

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

    What is this, a movie theater for ants?

    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.
