A few people have been asking, so I'm posting an update to make it clear.
All aspects of this Kickstarter project, from the video to the text to the update photos to the soundtrack samples, has been placed in the public domain. It can all be freely reused and modified with absolutely no restrictions, for any purpose, and no permission necessary.
Not like I could stop you from doing this even I wanted to (without installing 2 billion cameras in 2 billion homes). But I don't want to.
