WinMatrix XP - animated wallpapers on the desktop, showing the running code of the matrix, familiar to many from the same movie. The code is displayed in the background and does not close any desktop icons or windows of running applications. The program consumes little system resources and can be used even on old computers. The length of the ticker and the speed of their movement are adjustable. The size of the symbols and their variability can also be changed. It is possible to use two sets of matrix code and to automatically start the wallpaper at the start of the system.
