It seems like this might Work even better with a two sided OLED screen (2 screens back to back) rather than led array, for better resolution? I think that are sufficiently wide angle, at least the monochrome ones.
The centering issue could be solved by putting two led boards on top, back to back.Perhaps one board could shift the leds over by half to create an interlacing effect while doubling resolution.
There's gotta be some way to replace the rack-of-leds-spinner with something lighter. Mirrors? Acrylic light pipe matrix?
Creative. I probably have the persistence and interest to pull something like this off, but I lack the fantasy to come up with such cool projects. Luckily there's the internet to see what impressive stuff people come up with.
It really makes a huge difference in what you can get done with side projects. You probably have more interesting ideas than you think you do, but if having them doesn’t line up with having the time and energy to act on them (or even to just expand on them), they’ll fade away.
This would look better with the LEDs on a transparent PCB, right?
I wonder how they respond to being dunked in epoxy.

I wonder if it would be simpler to just spin two phone screens glued back-to-back. You get higher resolution in about the same weight. Bandwidth would be a problem though.
And even there, 12 Hz is probably pushing it in terms of flicker.
