Title of project is tentative because I think it may be in use. The goal with this is essentially to collect excellent ways of explaining particular topics. In particular, we're looking for, for example, an analogy that crystallize a particular concept for someone. For a given concept, there might be some activity or story or computer game or whatever that will fit a particular type of personality or learning style.

Basically, for a given concept we want to get the best (possibly (but probably "usually") several) explanation(s). for that concept and put them where they can be found.
