Here is a very cool and free Emulator of the Matrix Code....I checked it an it is virus free....
Not sure who made it cause it didnt come with no Read-Me Instructions so I made some for it....
I take no credit what so ever in making the Screensaver just the read me file is all and hope it'll help to who ever wants to install it, Here is a pic of it from my Desktop....Enjoy!!!!

Here's my link to download it from me....

Good...I like it.  

If it's the one I think it is, it's one from the Matrix disk. But for some reason it says invalid quickkey when I try to get it from the link provided. But the image looks the same as the one from the Matrix movie disk.

Whatever, the guy who made it  have done a great work!!

Do you even have the screensaver?
I tried the download link and it doesn't work
