A pretty cool live wallpaper
Falling Blocks Live Wallpaper — description
It is a live wallpaper of the Falling blocks game. It does not require you to manually control it. It automatically jumps to the position and rotation of the next block according to the blocks in the current screen. It is very interesting. When it is covered by the application or the screen is off. It pauses work, so it is low energy.
