Creative Idea Generation

I love Creating Passionate Users and Kathy has a great post that I'm going to have to try the next time we do do a large scale creative idea generating session. It's a Product Design Dinner Party. We generally attack these sessions with a group of people from various fields and with various levels of experience in a round-table set up. This will take a bit longer, but I think it will make for some outstanding ideas. What do you think?
