Animated Icons

Before to continue reading the descrption I want to make a warning: "THESE ANIMATED ICONS ARE ADICTIVES". Yes! Once you pass the mouse over the icon and see the animation you will continue doing this for a couple minutes. At least it happen to me! If you want to have any  motion on your screen or you are bored to se your static screen... this is what you need. 
This icons are used usually on programs like ObjectDock, Nexus Dock or any other software that handle PNG sequence icons to show animated icons.
