Interesting. I use something similar when I am training people. When I want the group to discuss something, I usually leave a relevant image up on the projector. When I do this, I find people stay on topic a lot more and the discussion is more fruitful. On a side note, images work better than having text up. Something about the image seems to work without distracting them from their discussion
