1. Find a concept, any concept!  Tell about it.  Provide links. (shortened link of course)
2. Explain why it should be become mass produced!
3. Random thoughts about the concept?
(PS From MsK:  I'm not sure what this student was thinking here and I didn't edit their idea at all except to add that cool pic....so we'll see where this takes us...)
