Create a starfield/particle river on RGB LED matrices with the Raspberry Pi

Instructables user ‘dearner’ has taken a Raspberry Pi, four 32×32 RGB LED matrix boards, an Adafruit RGB matrix HAT, a good extra power supply for the matrices and some smaller parts and created a long LED display. He’s then created some software to generate the starfield effect and put it on the Pi. The effect (which you can see below) is strangely beautiful. The whole thing is written up as a tutorial which you can see hereBeware: some of the inline Python code is not indented, so you might need to figure that out for yourself.

You can see the starfield in action below:
