[survey] Choosing a Seminar to Teach

I want to teach a seminar in ESG next semester, but all of my ideas require a fair amount of preparation, and I like them all too much to decide between them. So I want to hear your reactions: below are descriptions of the classes I'm trying to decide between. What sounds interesting to you, and are there any variations or related topics that you'd want in the classes?

FYI, non-MIT people are always welcome at my seminars and activities. I may also do parts of these as activities during January, when MIT becomes a seething mass of zany seminars, projects, and gatherings.
