I really love this app, so I decide to some 3D practice, and make a little animation, something like commercial of this beautiful icon.
By the way, you can suggest, what icon I should animate next. It can be yours, or just icon that you love, anything. Usually I get 2-3 comments, so you got pretty good chances, that I will pick your idea.
