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.
