This live wallpaper shows a tree sketch with a variety of static and moving elements like leaves, flowers, shadows, moon, clouds or snow. The scene is responsive to user inputs. This is the free demo version. The user may choose between several presets and select one of the atmospherical settings. Take a look at the screenshots. You may want to try the highly customizable full version where all features are unlocked and single elements may be activated/deactivated and colorized.
