Many TV shows have apps, but they're usually meant as nothing more than companions that encourage you to tune in. What if you could actually choose how the story is presented? Steven Soderbergh is trying just that. His upcoming HBO miniseries Mosaic will be accompanied by iOS app that gives you control over a branching narrative, letting you change how the story is told. And this isn't just a conventional show cut up into pieces. Soderbergh says he produced the story with the app in mind, and there are even different conclusions. While it won't be a Choose Your Own Adventure experience with big-name actors (Sharon Stone, Beau Bridges and Paul Reubens are part of the cast), it's likely as close as you'll get for a long while.
