Origami conference tag tags

Here's another cool tag tag application given to me by a friend who regularly attends the OrigamiUSA Annual Convention.

So, as origamists(?) walk around and encounter one another in physical space, they display this structured metadata about themselves re: an origami project they would like to learn or teach. This sort of tag tag seems ideally suited for a physical gathering at which attendees have (or desire) "atomic knowledge" -- i.e., discrete pieces of knowhow about an area of activity, combined with a common desire to learn new pieces and share pieces they already know.
