Plussing sessions provide an opportunity for project teams to share their ideas, progress, challenges, and next steps with the participants in the program on a monthly basis. (Plussing is a termed used at Pixar to mean "finding what's good about an idea and making it even better").
In the first plussing sessions early in the schedule, don't worry if you don't have anything to share. There will be time for that in the coming months. If you do have something to share, consider bringing sketches or other visuals to help describe your ideas. If you have several ideas for a project and haven't yet decided upon one, consider briefly describing them all. If you have work in progress, by all means bring pictures, artifacts or other materials to talk over.
The plussing sessions will be organized like little Maker Faires where a bunch of people are sharing their work at the same time, with their materials laid out on a table for discussion as others pass by.
Here are a few of the kinds of questions you might get during these sessions:
