I remember the guys at Big Block Games made this game in a 2 week sprint for charity where one of the artists or programmers had to be online at any time of the day:
It was completely streamed live and was really enjoyable, they'd work and chat to the watchers at the same time, answer any questions and give advice on what they were currently doing. Rather annoyingly it worked really well but I haven't seen anyone repeat anything similar since.
