I realized I’d never gotten around to posting a picture or video of the display station actually working. I’ve had this running for nearly a year now, first on a breadboard, and then via the shift register circuit board I had made. I mounted the LED’s to some smoked plexiglass, then build a simple box to put the entire mechanism in. A single higher output 5V power supply attaches to the Arduino and to the LED’s providing sufficient current for everything.
Here’s the display with an iPhone on the right for scale..
