Make a Matrix Screen With Pseudo-Random Number Generator





Introduction: Make a Matrix Screen With Pseudo-Random Number Generator

If you like the matrix, and have some spare time, you could make an endless program, that shows random numbers, as fast as the computer can run it, looking very similar to the matrix! It only takes about 5 minutes to prepare!

I was having a look around the Instructables site, and saw some Matrix screen makers.
I like writing computer programs, and one time decided to make one of these, and I am going to show you how!

You must have the Microsoft .NET Framework 3.5 installed to do this.

Please rate, it is my first instructable, and I want to know how I go.

If you do not have the Microsoft.NET Framework 3.5, you can easily download it from the Microsoft Download site (, and search for .NET 3.5.

I have made a new version that spits out random characters, instead of just numbers.

It DOES NOT show a screenshot of the matrix, or show a 3D screen. Just random letters. In green.

Step 1: Coding

You need to download the code file attached, and save it in to your my documents folder. If you are interested in computer programming, this program might be interesting to look at. You need to copy all of the italic text, and save it to a file called Program.txt.

using System; namespace Matrix_V2 { class Program { static void Main(string[] args) {
//Sets the text color to green
Console.ForegroundColor = ConsoleColor.Green;
//Create a string with some random characters
string random_characters = "£¤¥¦§¨©ª«¬®¯±²³´µ¶·¸¹ºΣΤΦΩαβδεμπστφABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz<,>.?/:;\"\'{[}]\\|`~0123456790-_=+!@#$%^&*() ";
//Get all of those characters and turn them into an "array"
char[] random_characters_array = random_characters.ToCharArray();
//Clear the screen Console.Clear();
//Writes details about the application to the console screen
Console.Title = "Matrix V2 - Press Ctrl+C to exit";
Console.WriteLine("Matrix V2");
Console.WriteLine("Written by Chris Ward");
Console.Write("Press any key to continue");
//Creates a pseudo-random generator
Random r = new Random();
//Creates a statement that runs forever
while (true) {
//Gets the ASCII character from the array, based on what the number is
//then runs the statement again... and again... etc.
} } } }

Step 2: Creating Batch File.

Open notepad again, and type this, only changing text if you know exactly what you are doing, and make sure it is all on one line, as I moved it on to separate lines so it would fit

 @C:\WINDOWS\Microsoft.NET\Framework\v3.5 \csc.exe /noconfig /nowarn:1701,1702
/errorreport:prompt /warn:4 /define:TRACE /reference:"C:\WINDOWS\Microsoft.NET\Framework
\v2.0.50727\System.dll" /filealign:512 /optimize- /target:exe /out:Matrix.EXE Program.txt

Then you must save it as a .BAT file, in the same location as the program.txt file.

Step 3: Running

Simply double click the batch file, and the command prompt window should close quickly. Once it has closed, the file should have been written (Matrix.EXE). Now all you have to do is run the program (Matrix.EXE), and the program will run.

If the file isn't created, add on a new line @pause to the batch file, then try running it again, then if there is detail on an error, post a comment and I will try to fix the problem. Any other problems? Just post a comment.

Step 4: Troubleshooting

 Error text: 'C:\WINDOWS\Microsoft.NET\Framework\v3.5'  is not recognized as an internal or external command, operable program or batch file'

* This is actually my fault, I made a mistake on the batch file. I will update the code on it, but to change it, there is a little space, just after the\v3.5 and before the \csc.exe. Just remove that space and run again. Alternatively you could download the code again

Any other problems? Post a message and I will get back to u asap.

    I copied the code and removed the space before \csc.exe and it ran very nicely. thanx for the matrix code, much more realistic than simply using the random number code.

    so i have to have the frame work in order for this to work, and i really dont want just random as letters and numbers, does it look exactly like it in the picture?

    It doesnt look exactly like in the picture, what you are describing seems to be correct. I am currently working on a version that is more similar to the picture, but i cant make it in 3d, no idea how, lol. I will upload a new picture soon.

    My batch file won't change into a exe file. Is this because I have framework 4.5?

    All this software users! Modifications of my version:
    #no data and keypress, fast running
    #maker error fixes(like spaces)
    # link:
    Than you!

    Not sure what you mean by it's fast running, it's all about the speed of the computer. If anything you'd want to slow it down so it doesn't chew up too much CPU. And what do you mean error fixes? I didn't realise there were any errors. I pulled your source and can't find any error handling

    i meaned errors in maker(look up!):P Like spaces!
    I removed author data and "press enter" to start

    Well it is actually against the licence that the code is released under to remove that line and not attribute in any other form, just add a comment or something around the top saying it's derived from my source

    Can you tell me where is the place of the code "Press Ctrl+C to exit"? I want to change the combination key "Ctrl+C" to another key. Thank
