Interactive films?

This Samsung site, Anyfilms has a go at providing an interactive film. It follows the common model of providing lots of pieces you can sequence yourself to make your "own" film, but it seems more sophisticated than the ones I've seen before. Creativity is limited because you have no idea what the pieces are as you arrange them, and even the title is selected for you. Am still looking for sites where the viewer's own content can be brought into the mix...
