he means a animated avatar. you can request one in GFX request section. you just have to tell what kind of animation you want. I'm not sure tho is format for animated avatars possible with sythe boards.
I wouldn't recommend copyrighting other people's work. Why don't you make your own instead? All you have to do is get an image and duplicate the layer and odd amount of times and add effects to each of those layers. Personally my favorite's are sprite renders. Just make them one by one. A good place to find sprites is www.planetrenders.com. Try it yourself and post a result
