I threw together a quick test of video on the LED screen. It's not great, but then again, it's only a 0.000512 megapixel display!
This was an ugly hack. A python program on a PC uses opencv to read video frames from a webcam, resize them to 32x24, then transmit the upper 16 rows of the image over a serial port at 1M baud. On the other end, an arduino nano collects the data into one of two ping-pong buffers while the other buffer is displayed on the LEDs.
With a diffusing screen, the video looks better to the eye, but on camera, the raw LEDs look better (although a little sparse).
I might be done with display tricks at this point. Maybe.
