Sweet hack, thanks for sharing. I remember playing in the dark with luminous paper as a kid - If I remember correctly, I would take a hacked up disposable camera and put various objects in front of the paper before triggering the flash.

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.
