This is a computer theme from "The Matrix" compiled by gtomega1. It consists of:

Wallpaper - This is fairly simple. If you want 800x600 resolution, extract 
matrix04-0800.jpg to C:/WINDOWS/Web/Wallpaper. If you want 1024x728 resolution, extract
matrix04-1024.jpg to the directory stated above.

Computer Sounds - Go to the Control Panel and select the "Sounds" icon. Use the file
names as a guide to which event it should be used for. Very straghtforward.

Screensaver - Extract the files matrixcodeemulator.scr and glyph.ani to the C:/WINDOWS
