I just read this post on the “Creating Passionate Users” website:

Build Something in 24 Hours.

It describes a “jam” strategy for creating something in a set amount of time, without the need to shift your brain back and forth between your different lives. It’s similar in concept to the 24 hour comic. Where it differs is that it involves working with a group of individuals to not only brainstorm but actually put pen to paper, hand to mouse, finger to guitar string, whatever. Lots of application. Just need a lodge and a couple of people to get started. Hmm.
