You may be interested in a new (kind of secret - but not really) interface for YouTube. It is called Warp. It allows you to swim from film to film in some kind of floaty film filled soup.
Hard to describe - but easy to use.
Go here to play.
As a writer and film maker it makes me think about the potential of using that interface to create a truly non-linear film. A story that starts in one place, but can grow into any direction. Cool stuff.
