Those of us at the Stanford d.school are all pretty obsessed with brainstorming and the role it plays in the creative process.  And I’ve thought about the effects of brainstorming and how to run a good brainstorming session for years, as this was one of the main themes that emerged from the research that Andy Hargadon and I did at IDEO — you can read about some of the main lessons we learned here and here in BusinessWeek.  But I will never think of brainstorms in quite the same way again after seeing this picture!
