While there is nothing revolutionary in "3D Matrix Saver", it is free and has an interesting options. As in other versions of Matrix Screensavers, you will see the familiar green running code. Although this program provides a set of functions. You can choose the speed settings, etc. Theme music is better than many other MIDI based soundtracks we have heard, but you can always turn off the music and sound effects. Fans Matrix clicks, who spent all their money on the theater will probably enjoy this screen saver.
