Return to The Matrix with this project recreation. The falling streams of green characters are strange yet calming. 

From Quora, the significance of The Matrix computer screen

1. Representation of Reality: The screen symbolizes the digital nature of the Matrix itself. It reflects how the simulated world is constructed and manipulated by the machines controlling humanity.
2. Alternative Perception: Characters like Neo and Morpheus use the screen to perceive the underlying code of the Matrix. It represents the ability to see beyond the illusion of the real world and understand the truth of their existence.
3. Coding Language: The characters are able to read the screen because it displays the Matrix's code, which is a visual representation of the program that constructs their reality. This code is often depicted in green characters on a black background, reminiscent of classic computer interfaces.

Or, it just makes a cool visualization.

This project displays high resolution video generated by an Adafruit Metro RP2350 or Adafruit Fruit Jam. The HSTX bus outputs DVI video which can be shown on an HDMI monitor. The Adafruit-DVI-HSTX library makes the project easy to write programs like this in Arduino, while displayio makes it easy in CircuitPython. No soldering required with the Fruit Jam!
