The shapeshifter online tool.

This tool named shapeshifter can be used online to create animated SVG and vector files.
The default tool can be found here.
The tool is not very easy to use but can easily understand if you know how to animate an SVG file.
The basic steps are importing SVG files and making changes to the parameter area.
Another web page with the beta tool can be found here.
This is more complex and lets you use more features.
