It sounds insane, but the array that drives it is functionally not that different from the array that individually causes LCD crystals to shift.

I have DLP parts sitting around because they're cool.

Edit pics:

Edit2 explanation: A white light is focused onto the DLP mirror chip through a kind of kaleidoscopic lens, I'll spare you the details on that. The individual microscopic mirrors are aligned with charges to bounce light. The mirror array pulses synced frames through the spinning color wheel to create a composite image. It's a fucking insane idea that barely works... and people like me, with low persistence of vision, are not fooled very well and we see color banding and all kinds of weird artifacting lol

There was an idea I read about, sorta along the same crazy track, (might have been Popular Science or something like 25 years ago) where they came up with an idea for a jet that didn't use traditional control surfaces like ailerons, but rather line the wings and fuselage in thousands of tiny flaps that would all be precisely computer controlled. It would be able to basically mold and shape the airstream around itself to make precise movements.

still used for a type of advanced microscopy.

There was a micromirror e-paper too. Though i don't think they got a reader on market. Got bought up by E Ink corp, like everythiing else e-paper.

I believe the crt projector doesnt have that issue

Yes, I could tell if dlp, whenever my eyes moved.

They fixed the issue by increasing the color changing frequency in led beamers.:)
