Thanks to the wonders of internet technologies and people who use them, I've found a participant's account from the Reverse Brainstorming session I did at University of Michigan, Ann Arbor, in 2009. The session was a part of my guest lecture about invention and innovation for students in a cross-disciplinary course on Smart Surfaces.
Peter Hall, the author of the blog, was a Senior studying industrial design. His post and pictures on Flicker can give you an idea of how a real session looks like.

Note that the group (pictured hard at work) used whiteboards, not flipcharts, to record problem statements. Overall, they generated 70 problems over 40 minutes.
