The Matrix Falling Code Effect in Notepad (Fun CMD Trick)

Short answer: you can make your screen fill with the green Matrix falling-code effect using a four-line Windows batch file, no software needed. Paste the code into Notepad, save it as a .bat, and run it. Here is the code, how it works, ways to customize it, and how to stop it, all completely harmless.

The Matrix batch code

1. Open Notepad.
2. Paste this exactly:

@echo off
color 02
:tricks
echo %random%%random%%random%%random%%random%%random%%random%
goto tricks

3. Save it as Matrix.bat (choose "All files" as the type so it does not save as .txt).
4. Double-click the file. Your command window fills with scrolling green numbers.

How it works

• @echo off hides the command prompt text so only the output shows.
• color 02 sets the window to black background, green text, the Matrix look.
• :tricks is a label, and goto tricks loops back to it forever.
• echo %random%... prints random numbers each loop, creating the falling stream.

Customize it

Change	How
Different color	Change 02 (e.g. 0A bright green, 0C red, 0B cyan)
Denser stream	Add more %random% on the echo line
Fullscreen	Press Alt+Enter while it runs

How to stop it

It loops forever, so to stop it just close the command window, or press Ctrl+C in the window and then any key. Nothing is installed or changed on your system, closing the window ends it completely.

Is it safe?

Yes, entirely. It only prints random numbers in its own window and touches nothing on your PC. This is the non-obvious point about batch "tricks": harmless ones like this just display things, but the same .bat format can run real commands, so only ever run a .bat you wrote or fully understand, never one someone sends you.
