Animated Icons make your app icons look fabulous by animating them with several unique and beautiful animations.
You can animate your icons by long-pressing on an empty area on your home screen. When you will long-press, a menu will pop up from where you will select 'Widgets' or something similar.
>> Then you will be presented with a list of widgets, from which list you will select 'Animated Icons'.
>> Then you will select the app whose icon you wish to animate.
>> Then you will choose your favourite animation, and voila!
Enjoy the animated icons!
Bonus Tip: You can also resize the widget in some launchers to enjoy super large icons with more HD animations!
