My $.02: The problem is a really great art project meant to push the web forward. I think we need more things like popcorn to make broadcast data driven, but I don't think popcorn is the thing that makes it all happen.
The site could use a better design, but basically this integrates user input (mouse, text) and external data and libraries to affect the video itself as it plays. Would be a good base for making videos like the one Arcade Fire + Google made, or ones with even more interactivity, since user input can also be saved and reused on subsequent plays, allowing the video to evolve over time based on collective user input. That's what I was planning to create with it, but didn't end up finishing that part...
If you have a single page app that is heavy on js, skip the demo video. Record some audio and have it actually use your app as it plays. Pretty cool stuff.
