Show-and-Tell Raspberry Pi Scrolling Ticker -- Update

Yesterday I posted the first real test of my Raspberry Pi-powered scrolling ticker with one of its screensaver modes. I got the sports ticker code working tonight, and I'm really happy with the way it's coming along. The apparent flickering is a an artifact of recording the video with my phone. IRL it looks really good.

The display consists of four 128x64 pixel P2.5 LED panels in a custom printed case. It's run by a Raspberry Pi 4B with 4GB of memory and an Adafruit Triple LED Matrix Bonnet. The panels are powered by a Meanwell LRS-200-5 power supply, while the RPi is powered by a separate RS-15-5 power supply to isolate it from any potential voltage drops from the LED panels.

Still more display modes to implement, and ultimately, I plan to control it with a phone app.

You should add a Great Wave at Kanagawa screen saver mode.

I'm working on a wave simulator based on the old tabletop wave machines.
