This is a very nice Winter Snow Trees 3D Live Wallpaper renderer with Open GL for smooth graphics.
Recommends a more powerfull device at least a dualcore for this wallpaper. This is tested with a Samsung Galaxy S2!
The live wallpaper is screen touch enabled so the screen is scrolling with your touch. The trees are swaying in the wind and snow is falling down. In setting you can change sky, quantity of snow and the snowflake type.
