Android: Surprisingly, Android doesn't have many apps that let you create your own live wallpaper. A new free app called Murtastic is among the easiest ways to do just that.
Each page of Murtastic has options to add text and set its position, change its colour or size, add background colours, and add new images in the background. The text appears in an animation that mimics each letter being typed. You can add multiple pages and then save it as a wallpaper. There's also an option to modify existing live wallpapers on your Android device.
