I’m NOT promoting Mixamo… I am not using any of their products but, they do have a fun new promotional video out for their upcoming Webinar: Bring Your Game to Life. They sell animated characters and tools to help build them.
I think the illustration of a radically different user interface is great. I think that is something that could be done with LEAP Motion. It is something like what a new user interface for building with Oculus Rift might look like… or so I imagine.
