Taking a quick look at a few js animation libraries that you might be interested in to create awesome animations.
Actually there are many more libraries that are available, but these are the ones that I looked at and recommend that you try.
In addition, I have a link to a cool SVG animation tool called Gear Generator that may be of interest to some of you.
