Modern parallel: My business partner and I have a weekly brainstorm on Tuesday night (not quite by campfire) that's focused on us coming up with wacky and crazy creative ideas. We often do it over wine, we let our imaginations run wild, we try to come up with extreme concoctions that might just be able to work, and we have a space to be creative and no idea is bad during that time. Surprisingly, we've found that this really helps our creativity for the other 99.9% of the work-week: sometimes, our crazy ideas come back to us (in more reasonable forms, less extreme) that we then implement and make happen! In other words: we realized, too much of our day-to-day work is concerned with tactical issues, so we've created a space around a virtual fire to unleash our creativity, which then helps us in the day-to-day. Maybe this work due to evolutionary forces on humans since these paleolithic days!
