Innovation was a short lived series (8 episodes) on PBS that “presented scenarios in which people are challenged to push disciplinary and design boundaries in order to create cutting-edge technology projects. These endeavors can inspire students’ curiosity and desire to participate actively in project design and building — so INNOVATION is ideally suited to be a starting point for project-based learning.”  I really like their teacher guide on this site that frames how to use this tool for project based lessons.
