In fact, the production of such a scene of snow is not complicated, it is the first principle of a black background for the screen to draw a random number of white spots (snow), and then make these snowflakes down constantly (re-drawing), repeated cycle, on the successful simulation of the snow scene. The following is a small program, you can modify some of the data to adjust the density of snowflakes and the speed of falling snowflakes.
