WinMatrix XP - These animated wallpapers are reminiscent of those found on the movies from which the matrix is sourced. There are no desktop icons or icons of open applications displayed in this background code. Even old computers can be used with the program, which consumes only minimal system resources. You can adjust the ticker's length and its speed on the fly. A number of different sizes and variability are available for symbols. A pair of matrix codes can be used on both ends of the wallpaper to automatically start it on the other hand.
