A live wallpaper with awesome gyro-based 3D parallax effect!
This live wallpaper shows collections of animated, interconnecting gears. It uses the built-in gyroscope to create a 3D parallax effect similar to what you may have seen in IOS7, but better! Not just a flat image, but several layers of 3D objects moving in a way that creates an immersive 3D effect.
The basic version of the app is free. The 3D parallax effect is fully functional, but only one scene and one theme (the blue one) are available. The full 'PRO' version is available as an in-app purchase from the settings menu, and will get you access to 3 additional scenes and 6 more color themes, as well as the option to create your own color themes.
Note that since this is a live wallpaper, there will not be an icon for it in the app launcher. After dowloading the app, install it by long-pressing on the home screen, then choose 'Live wallpapers', and select the Gears wallpaper from the list that is presented.
The wallpaper is only active when visible. It really doesn't do anything unless you can see it, so it's not too hard on the battery.
