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.

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
