Well, the thought I had was maybe a round-robin kind of affair. Say, someone started with a relatively simple idea, then passed it to the next person, who added to/modified it, then to the next, and so on, maybe for two rounds. I’m thinking we’d want to limit each turn in some way, like spend no more than two hours on your turn (less? more?). I think the feasibility of this is going to be affected by how many participants we have. Maybe it could be fun to save each iteration, too, so we can show its evolution (in keeping with the theme); maybe that could be the final album – each step in order.
