An online interactive Choose Your Own Adventure-style quest, conducted online, using Twitter polls. The audience collaborates to solve a complicated assignment. This is the first; the rest of the story will be played out over a series of chapters in September and October in this launch event. All of them will be fully online, but the Edinburgh audience will be the nerve centre of the challenge team. This is the start of something fun, and you won't have seen anything quite like it. Unless you've seen John Robertson's Dark Room. Which many of you have. But it's not quite the same as that, luckily.
