I really like this idea. I think it could combine well with the chance for students to create "narratives" around each proposed idea. This could allow students who may not feel technically inclined to participate and be an avenue for collaboration amongst students.
I am a big fan of the idea. I have watched "This Old House" (home improvement/contracting show)for years, having little/no handyman ability. The show "Ask This Old House" has a segment devoted to just this. It's more comical with the hosts, but having such little experience in the field, I gained alot of information and options to seek further information about what I learned. Link to some sessions with the information about the segments to which I refer, called "What is it?"(http://www.thisoldhouse.com/toh/tv/ask-toh/products-and-services/category/0,,4558,00.html)
