I imagine that you could improve the consistency and readability some by modeling the state of each pixel of paper. That way when the drum comes around you can compensate the exposure per pixel based on the current state to achieve better uniformity of display. In this way you could do exposure compensation on each row of output to make the display equally bright top to bottom. This would be similar to how a "no-refresh" epaper display works.
Maybe the same thing could be done with beads and something similar to the marble machines to replenish a screen of beads, then dump it when the time is invalid.

I've bought a couple of versions of his blackest black paint, and one of his whitest white, and they've all be extraordinarily good.
I have some of his "LIT - THE WORLD'S GLOWIEST GLOW PIGMENT", but I haven't used it yet. I have no doubt it'll be great as well.
(I have a vague plan to paint a motorcycle in Black4.0 to see if it's unreflective enough to evade the IR laser speed detectors cops use here...)
Once you've had this on the ceiling for a while, it's annoying to have to look for time on a nightstand or your wrist.
say, why don't you move mirrors but the whole laser?
