Presheaves on categories crop up everywhere! In this talk, I'll give a
gentle introduction to 2-categories, and discuss the notion of a
presheaf on a 2-category. In particular, we'll consider which
2-categories such a presheaf might take values in. Only a little
familiarity with the notion of a category will be assumed!
