An app to quickly create 3D animation

Hi! My team is working on an app called MashMe ( http://mash.me/ ) where we want to enable everybody to create fun animated videos. From the technical side, it is a markerless mocap solution on your regular webcam

Here is a video of MashMe in action http://youtu.be/nkD8rSV513A

How does this look to you? I would really appreciate any feedback you can give me
