Android Question Snow Fall Live Wallpaper


I want to create a simple live wallpaper with snow falling.

I do not like all the live wallpapers in the app store that have very defined snow flakes. I want the snow flakes to be blurry / out of focus.
Also most of the wallpapers do not have very good random falling patterns. Some fall straigth down in a line. Others are nice but have the above problem.
I also want to make one that does not take very much resources so it does not take much battery and results in a high FPS.

I have searched the forum but only found some very old topics.

Does somebody have an example or tutorial? Or any advices on what to use and what not to use or to avoid?

I am a B4A beginner but with some good direction or examples i may succeed :)
