Well, it looks like I'm going to have to publish a glossary of what I think a bunch of words mean, so as to be understood by those around me. I made up my own sense of "pathetic fallacy" and I appear to have done it again for bricoleur.

Rheingold's book gives a definition that is less abstract than the Lévi-Strauss-like concept given originally by tsuwm, but that is quite different from mine - A person who constructs things by random messing around without following an explicit plan. Rheingold also describes a bricoleur as "a kind of intuitive technician who plays with concepts and objects in order to learn about them."

So, I don't think Macgyver qualifies, and hopefully this definition will actually get hung in the dusty coat-closet of my mind without getting as askew on the hanger as it was.
