Armin Rehberger made an awesome, colorful, scrolling LED sign.
This bright animated sign uses 4 8×32 LED-pixel matrixes and scrolls not only horizontally but vertically as well. It’s controlled using a Teensy 4.0 and uses the OCTOWS2811 library.
With a sign as bright as this, you might need to wear shades.
