Have you seen Hollywood movie “Matrix” ? You must have liked those monitors with green code falling continuously. Looks like cool hacker/coder desktop! After movie went to box office, many matrix screensavers were out for windows. You want one for Linux? Like the one below?
Yes, thats possible. You can have such matrix like desktop in Linux terminal too. In very simple two steps.
Step 1 :
Install cmatrix package using YUM or APT depending on your Linux distro.
If you dont have YUM repository configured then you can download standalone file (check Sourceforge page if this link is broken). Then follow below commands to set it up from source code.
- Install packages : gcc, make, autoconf, automake ncurses-devel
- Download above mentioned file, un-zip, un-tar it and goto unpacked directory cmatrix-1.2a
- Within cmatrix directory execute below commands.

Then configure and make ready to install.
